Is it possible not to have a hypothesis in your thesis? [closed]

I have been working on a research report in which forecasting is done on the basis of data, followed by an interpretation of the forecasted results.

Is it possible to have that kind of research without hypothesizing any statement?

If this question is off-topic kindly recommend a suitable community.

As a statistician, I'm inclined to say "no, you can't" as a short answer. Reason for this is simple: even in complete random datasets on average 5% of the correlations will be significant when tested in a model. So if you rely on only the data to make any kind of interpretation on association of variables, you're bound to publish false positives. This has been discussed for decades, eg this rather strong opinion of Ioannidis (2005) :

http://journals.plos.org/plosmedicine/article?id=10.1371/journal.pmed.0020124

Bias can entail manipulation in the analysis or reporting of findings. Selective or distorted reporting is a typical form of such bias.

If you don't formulate a hypothesis and still interprete the data, you're -probably unintentionally- reporting selectively. You select from the analysis those results that tell a story, and in doing so, you're likely to report something that isn't a solid association or relation.

That said, you don't always have to formulate a specific hypothesis. For example, if you compare multiple methods on efficiency, you don't have to hypothesize beforehand which one is going to be the best. But the statistical test you use for comparison, will imply a "null hypothesis" that there is no real difference between all methods. Also this is "formulating a hypothesis" merely by the choice of analysis tools.

And this is even more important to realize: you might not formulate a hypothesis explicitly, but the nature of the statistical tools you use to come to your interpretation, will imply a set of rather rigid hypotheses and assumptions. You need to be aware of those hypotheses and also of those assumptions.

Because that's something I see far too often: people not explicitly formulating a hypothesis, still interpreting results from a statistical methodology, but failing to realize that their data does not meet the assumptions of that methodology. And that invalidates your entire interpretation.

This problem is even more stringent when forecasting. If you use regression models, you should be aware that predictions outside the boundaries of the original data cannot be interpreted. The uncertainty on those predictions is simply too big. If you use spline methods, you can even get into trouble at the edge of your original data. So definitely in the case of forecasting I would write out both the goal of the research and what you expect the predictions to show, including the scientific reason why. Only in those cases you can use forecasts as some form of evidence for or against the expected relation. If you don't do that, your forecasting model might as well be a fancy random number generator.

So in conclusion: even if your research goal isn't necessarily a defined hypothesis, you still need to formulate the hypotheses you want to test before carrying out the actual statistical tests.

And in all honesty, writing down what you expect to see is always a good idea, even if it's only to order your own thoughts.

• 1 +1 This is a really important point and a core principle of the scientific method, but for some reason many people either ignore it (out of convenience) or do not know about it. –  101010111100 Commented Jun 14, 2017 at 18:38
• There are fields - especially in Engineering - where results do not depend on a statistical analysis so as non-statistician, I would say, yes you can write a thesis without a hypothesis. –  o4tlulz Commented Jun 15, 2017 at 4:04
• 1 @Kevin That's using cross-validation, an often used statistical technique with its own assumptions. If you do that, you have to keep in mind that your training data and testing data have to be completely independent, or any hypothesis testing (yes, also there you test a hypothesis) is invalid. Independence is one of the most important assumptions in about every common statistical technique. –  Joris Meys Commented Jun 15, 2017 at 8:47
• 1 @Ooker I always tell my students to only use methods they know and understand. You can't know everything about statistics. But what you need to know, is all the details of the techniques you use yourself. And in any case every student should have the knowledge of the basic tests used in the majority of papers. Because if you don't understand those, there's no way you can evaluate yourself whether the conclusion in a paper actually makes sense. –  Joris Meys Commented Jun 15, 2017 at 8:51

What Is A Research (Scientific) Hypothesis? A plain-language explainer + examples

By:  Derek Jansen (MBA)  | Reviewed By: Dr Eunice Rautenbach | June 2020

If you’re new to the world of research, or it’s your first time writing a dissertation or thesis, you’re probably noticing that the words “research hypothesis” and “scientific hypothesis” are used quite a bit, and you’re wondering what they mean in a research context .

“Hypothesis” is one of those words that people use loosely, thinking they understand what it means. However, it has a very specific meaning within academic research. So, it’s important to understand the exact meaning before you start hypothesizing. 

Research Hypothesis 101

• What is a hypothesis ?
• What is a research hypothesis (scientific hypothesis)?
• Requirements for a research hypothesis
• Definition of a research hypothesis
• The null hypothesis

What is a hypothesis?

Let’s start with the general definition of a hypothesis (not a research hypothesis or scientific hypothesis), according to the Cambridge Dictionary:

Hypothesis: an idea or explanation for something that is based on known facts but has not yet been proved.

In other words, it’s a statement that provides an explanation for why or how something works, based on facts (or some reasonable assumptions), but that has not yet been specifically tested . For example, a hypothesis might look something like this:

Hypothesis: sleep impacts academic performance.

This statement predicts that academic performance will be influenced by the amount and/or quality of sleep a student engages in – sounds reasonable, right? It’s based on reasonable assumptions , underpinned by what we currently know about sleep and health (from the existing literature). So, loosely speaking, we could call it a hypothesis, at least by the dictionary definition.

But that’s not good enough…

Unfortunately, that’s not quite sophisticated enough to describe a research hypothesis (also sometimes called a scientific hypothesis), and it wouldn’t be acceptable in a dissertation, thesis or research paper . In the world of academic research, a statement needs a few more criteria to constitute a true research hypothesis .

What is a research hypothesis?

A research hypothesis (also called a scientific hypothesis) is a statement about the expected outcome of a study (for example, a dissertation or thesis). To constitute a quality hypothesis, the statement needs to have three attributes – specificity , clarity and testability .

Let’s take a look at these more closely.

Need a helping hand?

Hypothesis Essential #1: Specificity & Clarity

A good research hypothesis needs to be extremely clear and articulate about both what’ s being assessed (who or what variables are involved ) and the expected outcome (for example, a difference between groups, a relationship between variables, etc.).

Let’s stick with our sleepy students example and look at how this statement could be more specific and clear.

Hypothesis: Students who sleep at least 8 hours per night will, on average, achieve higher grades in standardised tests than students who sleep less than 8 hours a night.

As you can see, the statement is very specific as it identifies the variables involved (sleep hours and test grades), the parties involved (two groups of students), as well as the predicted relationship type (a positive relationship). There’s no ambiguity or uncertainty about who or what is involved in the statement, and the expected outcome is clear.

Contrast that to the original hypothesis we looked at – “Sleep impacts academic performance” – and you can see the difference. “Sleep” and “academic performance” are both comparatively vague , and there’s no indication of what the expected relationship direction is (more sleep or less sleep). As you can see, specificity and clarity are key.

Hypothesis Essential #2: Testability (Provability)

A statement must be testable to qualify as a research hypothesis. In other words, there needs to be a way to prove (or disprove) the statement. If it’s not testable, it’s not a hypothesis – simple as that.

For example, consider the hypothesis we mentioned earlier:

Hypothesis: Students who sleep at least 8 hours per night will, on average, achieve higher grades in standardised tests than students who sleep less than 8 hours a night.  

We could test this statement by undertaking a quantitative study involving two groups of students, one that gets 8 or more hours of sleep per night for a fixed period, and one that gets less. We could then compare the standardised test results for both groups to see if there’s a statistically significant difference. 

Again, if you compare this to the original hypothesis we looked at – “Sleep impacts academic performance” – you can see that it would be quite difficult to test that statement, primarily because it isn’t specific enough. How much sleep? By who? What type of academic performance?

So, remember the mantra – if you can’t test it, it’s not a hypothesis 🙂

Defining A Research Hypothesis

You’re still with us? Great! Let’s recap and pin down a clear definition of a hypothesis.

A research hypothesis (or scientific hypothesis) is a statement about an expected relationship between variables, or explanation of an occurrence, that is clear, specific and testable.

So, when you write up hypotheses for your dissertation or thesis, make sure that they meet all these criteria. If you do, you’ll not only have rock-solid hypotheses but you’ll also ensure a clear focus for your entire research project.

What about the null hypothesis?

You may have also heard the terms null hypothesis , alternative hypothesis, or H-zero thrown around. At a simple level, the null hypothesis is the counter-proposal to the original hypothesis.

For example, if the hypothesis predicts that there is a relationship between two variables (for example, sleep and academic performance), the null hypothesis would predict that there is no relationship between those variables.

At a more technical level, the null hypothesis proposes that no statistical significance exists in a set of given observations and that any differences are due to chance alone.

And there you have it – hypotheses in a nutshell.

It is a very good explanation. However, it limits hypotheses to statistically tasteable ideas. What about for qualitative researches or other researches that involve quantitative data that don’t need statistical tests?

In qualitative research, one typically uses propositions, not hypotheses.

How to Write a Hypothesis – Steps & Tips

Published by Alaxendra Bets at August 14th, 2021 , Revised On October 26, 2023

What is a Research Hypothesis?

You can test a research statement with the help of experimental or theoretical research, known as a hypothesis.

If you want to find out the similarities, differences, and relationships between variables, you must write a testable hypothesis before compiling the data, performing analysis, and generating results to complete.

The data analysis and findings will help you test the hypothesis and see whether it is true or false. Here is all you need to know about how to write a hypothesis for a  dissertation .

Research Hypothesis Definition

Not sure what the meaning of the research hypothesis is?

A research hypothesis predicts an answer to the research question  based on existing theoretical knowledge or experimental data.

Some studies may have multiple hypothesis statements depending on the research question(s).  A research hypothesis must be based on formulas, facts, and theories. It should be testable by data analysis, observations, experiments, or other scientific methodologies that can refute or support the statement.

Variables in Hypothesis

Developing a hypothesis is easy. Most research studies have two or more variables in the hypothesis, particularly studies involving correlational and experimental research. The researcher can control or change the independent variable(s) while measuring and observing the independent variable(s).

“How long a student sleeps affects test scores.”

In the above statement, the dependent variable is the test score, while the independent variable is the length of time spent in sleep. Developing a hypothesis will be easy if you know your research’s dependent and independent variables.

Once you have developed a thesis statement, questions such as how to write a hypothesis for the dissertation and how to test a research hypothesis become pretty straightforward.

Step-by-Step Guide on How to Write a Hypothesis

Here are the steps involved in how to write a hypothesis for a dissertation.

Step 1: Start with a Research Question

• Begin by asking a specific question about a topic of interest.
• This question should be clear, concise, and researchable.

Example: Does exposure to sunlight affect plant growth?

Step 2: Do Preliminary Research

• Before formulating a hypothesis, conduct background research to understand existing knowledge on the topic.
• Familiarise yourself with prior studies, theories, or observations related to the research question.

Step 3: Define Variables

• Independent Variable (IV): The factor that you change or manipulate in an experiment.
• Dependent Variable (DV): The factor that you measure.

Example: IV: Amount of sunlight exposure (e.g., 2 hours/day, 4 hours/day, 8 hours/day) DV: Plant growth (e.g., height in centimetres)

Step 4: Formulate the Hypothesis

• A hypothesis is a statement that predicts the relationship between variables.
• It is often written as an “if-then” statement.

Example: If plants receive more sunlight, then they will grow taller.

Step 5: Ensure it is Testable

A good hypothesis is empirically testable. This means you should be able to design an experiment or observation to test its validity.

Example: You can set up an experiment where plants are exposed to varying amounts of sunlight and then measure their growth over a period of time.

Step 6: Consider Potential Confounding Variables

• Confounding variables are factors other than the independent variable that might affect the outcome.
• It is important to identify these to ensure that they do not skew your results.

Example: Soil quality, water frequency, or type of plant can all affect growth. Consider keeping these constant in your experiment.

Step 7: Write the Null Hypothesis

• The null hypothesis is a statement that there is no effect or no relationship between the variables.
• It is what you aim to disprove or reject through your research.

Example: There is no difference in plant growth regardless of the amount of sunlight exposure.

Step 8: Test your Hypothesis

Design an experiment or conduct observations to test your hypothesis.

Example: Grow three sets of plants: one set exposed to 2 hours of sunlight daily, another exposed to 4 hours, and a third exposed to 8 hours. Measure and compare their growth after a set period.

Step 9: Analyse the Results

After testing, review your data to determine if it supports your hypothesis.

Step 10: Draw Conclusions

• Based on your findings, determine whether you can accept or reject the hypothesis.
• Remember, even if you reject your hypothesis, it’s a valuable result. It can guide future research and refine questions.

Three Ways to Phrase a Hypothesis

Try to use “if”… and “then”… to identify the variables. The independent variable should be present in the first part of the hypothesis, while the dependent variable will form the second part of the statement. Consider understanding the below research hypothesis example to create a specific, clear, and concise research hypothesis;

If an obese lady starts attending Zomba fitness classes, her health will improve.

In academic research, you can write the predicted variable relationship directly because most research studies correlate terms.

The number of Zomba fitness classes attended by the obese lady has a positive effect on health.

If your research compares two groups, then you can develop a hypothesis statement on their differences.

An obese lady who attended most Zumba fitness classes will have better health than those who attended a few.

How to Write a Null Hypothesis

If a statistical analysis is involved in your research, then you must create a null hypothesis. If you find any relationship between the variables, then the null hypothesis will be the default position that there is no relationship between them. H0 is the symbol for the null hypothesis, while the hypothesis is represented as H1. The null hypothesis will also answer your question, “How to test the research hypothesis in the dissertation.”

H0: The number of Zumba fitness classes attended by the obese lady does not affect her health.

H1: The number of Zumba fitness classes attended by obese lady positively affects health.

Hypothesis Examples

Research Question: Does the amount of sunlight a plant receives affect its growth? Hypothesis: Plants that receive more sunlight will grow taller than plants that receive less sunlight.

Research Question: Do students who eat breakfast perform better in school exams than those who don’t? Hypothesis: Students who eat a morning breakfast will score higher on school exams compared to students who skip breakfast.

Research Question: Does listening to music while studying impact a student’s ability to retain information? Hypothesis 1 (Directional): Students who listen to music while studying will retain less information than those who study in silence. Hypothesis 2 (Non-directional): There will be a difference in information retention between students who listen to music while studying and those who study in silence.

Frequently Asked Questions

What are the 5 rules for writing a good hypothesis.

• Clear Statement: State a clear relationship between variables.
• Testable: Ensure it can be investigated and measured.
• Specific: Avoid vague terms, be precise in predictions.
• Falsifiable: Design to allow potential disproof.
• Relevant: Address research question and align with existing knowledge.

What is a hypothesis in simple words?

A hypothesis is an educated guess or prediction about something that can be tested. It is a statement that suggests a possible explanation for an event or phenomenon based on prior knowledge or observation. Scientists use hypotheses as a starting point for experiments to discover if they are true or false.

What is the hypothesis and examples?

A hypothesis is a testable prediction or explanation for an observation or phenomenon. For example, if plants are given sunlight, then they will grow. In this case, the hypothesis suggests that sunlight has a positive effect on plant growth. It can be tested by experimenting with plants in varying light conditions.

What is the hypothesis in research definition?

A hypothesis in research is a clear, testable statement predicting the possible outcome of a study based on prior knowledge and observation. It serves as the foundation for conducting experiments or investigations. Researchers test the validity of the hypothesis to draw conclusions and advance knowledge in a particular field.

Why is it called a hypothesis?

The term “hypothesis” originates from the Greek word “hypothesis,” which means “base” or “foundation.” It’s used to describe a foundational statement or proposition that can be tested. In scientific contexts, it denotes a tentative explanation for a phenomenon, serving as a starting point for investigation or experimentation.

• Collecting Data

A hypothesis is a tentative statement about the relationship between two or more variables. It is a specific, testable prediction about what you expect to happen in a study. It is a preliminary answer to your question that helps guide the research process.

Consider a study designed to examine the relationship between sleep deprivation and test performance. The hypothesis might be: "This study is designed to assess the hypothesis that sleep-deprived people will perform worse on a test than individuals who are not sleep-deprived."

At a Glance

A hypothesis is crucial to scientific research because it offers a clear direction for what the researchers are looking to find. This allows them to design experiments to test their predictions and add to our scientific knowledge about the world. This article explores how a hypothesis is used in psychology research, how to write a good hypothesis, and the different types of hypotheses you might use.

The Hypothesis in the Scientific Method

In the scientific method , whether it involves research in psychology, biology, or some other area, a hypothesis represents what the researchers think will happen in an experiment. The scientific method involves the following steps:

• Forming a question
• Performing background research
• Creating a hypothesis
• Designing an experiment
• Collecting data
• Analyzing the results
• Drawing conclusions
• Communicating the results

The hypothesis is a prediction, but it involves more than a guess. Most of the time, the hypothesis begins with a question which is then explored through background research. At this point, researchers then begin to develop a testable hypothesis.

Unless you are creating an exploratory study, your hypothesis should always explain what you  expect  to happen.

In a study exploring the effects of a particular drug, the hypothesis might be that researchers expect the drug to have some type of effect on the symptoms of a specific illness. In psychology, the hypothesis might focus on how a certain aspect of the environment might influence a particular behavior.

Remember, a hypothesis does not have to be correct. While the hypothesis predicts what the researchers expect to see, the goal of the research is to determine whether this guess is right or wrong. When conducting an experiment, researchers might explore numerous factors to determine which ones might contribute to the ultimate outcome.

In many cases, researchers may find that the results of an experiment  do not  support the original hypothesis. When writing up these results, the researchers might suggest other options that should be explored in future studies.

In many cases, researchers might draw a hypothesis from a specific theory or build on previous research. For example, prior research has shown that stress can impact the immune system. So a researcher might hypothesize: "People with high-stress levels will be more likely to contract a common cold after being exposed to the virus than people who have low-stress levels."

In other instances, researchers might look at commonly held beliefs or folk wisdom. "Birds of a feather flock together" is one example of folk adage that a psychologist might try to investigate. The researcher might pose a specific hypothesis that "People tend to select romantic partners who are similar to them in interests and educational level."

Elements of a Good Hypothesis

So how do you write a good hypothesis? When trying to come up with a hypothesis for your research or experiments, ask yourself the following questions:

• Is your hypothesis based on your research on a topic?
• Can your hypothesis be tested?
• Does your hypothesis include independent and dependent variables?

Before you come up with a specific hypothesis, spend some time doing background research. Once you have completed a literature review, start thinking about potential questions you still have. Pay attention to the discussion section in the  journal articles you read . Many authors will suggest questions that still need to be explored.

How to Formulate a Good Hypothesis

To form a hypothesis, you should take these steps:

• Collect as many observations about a topic or problem as you can.
• Evaluate these observations and look for possible causes of the problem.
• Create a list of possible explanations that you might want to explore.
• After you have developed some possible hypotheses, think of ways that you could confirm or disprove each hypothesis through experimentation. This is known as falsifiability.

In the scientific method ,  falsifiability is an important part of any valid hypothesis. In order to test a claim scientifically, it must be possible that the claim could be proven false.

Students sometimes confuse the idea of falsifiability with the idea that it means that something is false, which is not the case. What falsifiability means is that  if  something was false, then it is possible to demonstrate that it is false.

One of the hallmarks of pseudoscience is that it makes claims that cannot be refuted or proven false.

The Importance of Operational Definitions

A variable is a factor or element that can be changed and manipulated in ways that are observable and measurable. However, the researcher must also define how the variable will be manipulated and measured in the study.

Operational definitions are specific definitions for all relevant factors in a study. This process helps make vague or ambiguous concepts detailed and measurable.

For example, a researcher might operationally define the variable " test anxiety " as the results of a self-report measure of anxiety experienced during an exam. A "study habits" variable might be defined by the amount of studying that actually occurs as measured by time.

These precise descriptions are important because many things can be measured in various ways. Clearly defining these variables and how they are measured helps ensure that other researchers can replicate your results.

Replicability

One of the basic principles of any type of scientific research is that the results must be replicable.

Replication means repeating an experiment in the same way to produce the same results. By clearly detailing the specifics of how the variables were measured and manipulated, other researchers can better understand the results and repeat the study if needed.

Some variables are more difficult than others to define. For example, how would you operationally define a variable such as aggression ? For obvious ethical reasons, researchers cannot create a situation in which a person behaves aggressively toward others.

To measure this variable, the researcher must devise a measurement that assesses aggressive behavior without harming others. The researcher might utilize a simulated task to measure aggressiveness in this situation.

Hypothesis Checklist

• Does your hypothesis focus on something that you can actually test?
• Does your hypothesis include both an independent and dependent variable?
• Can you manipulate the variables?
• Can your hypothesis be tested without violating ethical standards?

The hypothesis you use will depend on what you are investigating and hoping to find. Some of the main types of hypotheses that you might use include:

• Simple hypothesis : This type of hypothesis suggests there is a relationship between one independent variable and one dependent variable.
• Complex hypothesis : This type suggests a relationship between three or more variables, such as two independent and dependent variables.
• Null hypothesis : This hypothesis suggests no relationship exists between two or more variables.
• Alternative hypothesis : This hypothesis states the opposite of the null hypothesis.
• Statistical hypothesis : This hypothesis uses statistical analysis to evaluate a representative population sample and then generalizes the findings to the larger group.
• Logical hypothesis : This hypothesis assumes a relationship between variables without collecting data or evidence.

A hypothesis often follows a basic format of "If {this happens} then {this will happen}." One way to structure your hypothesis is to describe what will happen to the  dependent variable  if you change the  independent variable .

The basic format might be: "If {these changes are made to a certain independent variable}, then we will observe {a change in a specific dependent variable}."

A few examples of simple hypotheses:

• "Students who eat breakfast will perform better on a math exam than students who do not eat breakfast."
• "Students who experience test anxiety before an English exam will get lower scores than students who do not experience test anxiety."​
• "Motorists who talk on the phone while driving will be more likely to make errors on a driving course than those who do not talk on the phone."
• "Children who receive a new reading intervention will have higher reading scores than students who do not receive the intervention."

Examples of a complex hypothesis include:

• "People with high-sugar diets and sedentary activity levels are more likely to develop depression."
• "Younger people who are regularly exposed to green, outdoor areas have better subjective well-being than older adults who have limited exposure to green spaces."

Examples of a null hypothesis include:

• "There is no difference in anxiety levels between people who take St. John's wort supplements and those who do not."
• "There is no difference in scores on a memory recall task between children and adults."
• "There is no difference in aggression levels between children who play first-person shooter games and those who do not."

Examples of an alternative hypothesis:

• "People who take St. John's wort supplements will have less anxiety than those who do not."
• "Adults will perform better on a memory task than children."
• "Children who play first-person shooter games will show higher levels of aggression than children who do not." 

Collecting Data on Your Hypothesis

Once a researcher has formed a testable hypothesis, the next step is to select a research design and start collecting data. The research method depends largely on exactly what they are studying. There are two basic types of research methods: descriptive research and experimental research.

Descriptive Research Methods

Descriptive research such as  case studies ,  naturalistic observations , and surveys are often used when  conducting an experiment is difficult or impossible. These methods are best used to describe different aspects of a behavior or psychological phenomenon.

Once a researcher has collected data using descriptive methods, a  correlational study  can examine how the variables are related. This research method might be used to investigate a hypothesis that is difficult to test experimentally.

Experimental Research Methods

Experimental methods  are used to demonstrate causal relationships between variables. In an experiment, the researcher systematically manipulates a variable of interest (known as the independent variable) and measures the effect on another variable (known as the dependent variable).

Unlike correlational studies, which can only be used to determine if there is a relationship between two variables, experimental methods can be used to determine the actual nature of the relationship—whether changes in one variable actually  cause  another to change.

The hypothesis is a critical part of any scientific exploration. It represents what researchers expect to find in a study or experiment. In situations where the hypothesis is unsupported by the research, the research still has value. Such research helps us better understand how different aspects of the natural world relate to one another. It also helps us develop new hypotheses that can then be tested in the future.

How to Write a Strong Hypothesis | Guide & Examples

Published on 6 May 2022 by Shona McCombes .

A hypothesis is a statement that can be tested by scientific research. If you want to test a relationship between two or more variables, you need to write hypotheses before you start your experiment or data collection.

Table of contents

What is a hypothesis, developing a hypothesis (with example), hypothesis examples, frequently asked questions about writing hypotheses.

A hypothesis states your predictions about what your research will find. It is a tentative answer to your research question that has not yet been tested. For some research projects, you might have to write several hypotheses that address different aspects of your research question.

A hypothesis is not just a guess – it should be based on existing theories and knowledge. It also has to be testable, which means you can support or refute it through scientific research methods (such as experiments, observations, and statistical analysis of data).

Variables in hypotheses

Hypotheses propose a relationship between two or more variables . An independent variable is something the researcher changes or controls. A dependent variable is something the researcher observes and measures.

In this example, the independent variable is exposure to the sun – the assumed cause . The dependent variable is the level of happiness – the assumed effect .

Prevent plagiarism, run a free check.

Step 1: ask a question.

Writing a hypothesis begins with a research question that you want to answer. The question should be focused, specific, and researchable within the constraints of your project.

Step 2: Do some preliminary research

Your initial answer to the question should be based on what is already known about the topic. Look for theories and previous studies to help you form educated assumptions about what your research will find.

At this stage, you might construct a conceptual framework to identify which variables you will study and what you think the relationships are between them. Sometimes, you’ll have to operationalise more complex constructs.

Step 3: Formulate your hypothesis

Now you should have some idea of what you expect to find. Write your initial answer to the question in a clear, concise sentence.

Step 4: Refine your hypothesis

You need to make sure your hypothesis is specific and testable. There are various ways of phrasing a hypothesis, but all the terms you use should have clear definitions, and the hypothesis should contain:

• The relevant variables
• The specific group being studied
• The predicted outcome of the experiment or analysis

Step 5: Phrase your hypothesis in three ways

To identify the variables, you can write a simple prediction in if … then form. The first part of the sentence states the independent variable and the second part states the dependent variable.

In academic research, hypotheses are more commonly phrased in terms of correlations or effects, where you directly state the predicted relationship between variables.

If you are comparing two groups, the hypothesis can state what difference you expect to find between them.

Step 6. Write a null hypothesis

If your research involves statistical hypothesis testing , you will also have to write a null hypothesis. The null hypothesis is the default position that there is no association between the variables. The null hypothesis is written as H 0 , while the alternative hypothesis is H 1 or H a .

Hypothesis testing is a formal procedure for investigating our ideas about the world using statistics. It is used by scientists to test specific predictions, called hypotheses , by calculating how likely it is that a pattern or relationship between variables could have arisen by chance.

A hypothesis is not just a guess. It should be based on existing theories and knowledge. It also has to be testable, which means you can support or refute it through scientific research methods (such as experiments, observations, and statistical analysis of data).

A research hypothesis is your proposed answer to your research question. The research hypothesis usually includes an explanation (‘ x affects y because …’).

A statistical hypothesis, on the other hand, is a mathematical statement about a population parameter. Statistical hypotheses always come in pairs: the null and alternative hypotheses. In a well-designed study , the statistical hypotheses correspond logically to the research hypothesis.

What Is the Hypothesis in a Dissertation?

Types of Research Hypotheses

Your dissertation hypothesis is the prediction statement based on the theory that you are researching in your study. Doctoral candidates test their hypotheses in their dissertations, their original research project that they write and defend in order to graduate. Here, you will learn about hypothesis types, writing and testing for your dissertation and hypothesis examples.

In your dissertation, you may create a hypothesis based on your research that predicts a relationship, called an "alternative" or "research" hypothesis. To balance your findings, you will also create a "null" hypothesis, which claims that the relationship that is to be proven in the research hypothesis does not exist. According to Alan Agresti and Barbara Finlay in “Statistical Methods for the Social Sciences,” the null is directly tested and predicts no effect, and the alternative contradicts the null and predicts an effect.

There can also be types of research hypotheses. As indicated in Research Methods Knowledge Base, a "one-tailed" hypothesis specifies a direction, either an increase or a decrease, while a "two-tailed" hypothesis does not specify a direction, only a change.

You must write your dissertation hypotheses before you collect and analyze your data. A useful hypothesis as testable and should include the independent variable, which you control, and the dependent variable, which is observed or measured based on the independent variable. For example, taking media consumption of violence as the independent variable and aggression as the dependent variable, the null hypothesis could state, “Media consumption of violence has no effect on aggression,” while the alternative hypothesis would state, “Media consumption of violence has an effect on aggression.” Similarly, if you wanted to create a one-tailed hypothesis, you would indicate a direction, such as, “Media consumption of violence increases aggression." Make sure that your statements are brief and straight-to-the-point and keep in mind the results you will measure in your study.

Research Methods Knowledge Base states that hypothesis testing assumes that both mutually exclusive hypotheses (research and null) exhaust every possible outcome and in the end, one is accepted and the other is rejected. When you analyze your data, you conclude whether you reject your null hypothesis and accept your alternative or fail to reject your null.

A dissertation can test a very broad range of hypotheses, depending on the discipline and focus of the writer. For example Antoinette Hill from Our Lady of the Lake University lent her research hypothesis to the title of her dissertation, "Are There Differences in Leadership Styles at Local, State, and National/Federal Levels among Advocates for People with Disabilities?" Her hypothesis used leadership as the independent variable and level of advocacy for people with disabilities as the dependent variable. Simply looking through the titles of dissertations published at a university of college each year can provide a long list of examples of a variety of hypotheses and ways to present them.

“The central question that you ask or hypothesis you frame drives your research: it defines your purpose.” Bryan Greetham, How to Write Your Undergraduate Dissertation

This page gives some help and guidance in developing a realistic research question. It also considers the role of sub-questions and how these can influence your methodological choices. 

Choosing your research topic

You may have been provided with a list of potential topics or even specific questions to choose from. It is more common for you to have to come up with your own ideas and then refine them with the help of your tutor. This is a crucial decision as you will be immersing yourself in it for a long time.

Some students struggle to find a topic that is sufficiently significant and yet researchable within the limitations of an undergraduate project. You may feel overwhelmed by the freedom to choose your own topic but you could get ideas by considering the following:

Choose a topic that you find interesting . This may seem obvious but a lot of students go for what they think will be easy over what they think will be interesting - and regret it when they realise nothing is particularly easy and they are bored by the work. Think back over your lectures or talks from visiting speakers - was there anything you really enjoyed? Was there anything that left you with questions?

Choose something distinct . Whilst at undergraduate level you do not have to find something completely unique, if you find something a bit different you have more opportunity to come to some interesting conclusions. Have you some unique experiences that you can bring: personal biography, placements, study abroad etc?

Don't make your topic too wide . If your topic is too wide, it will be harder to develop research questions that you can actually answer in the context of a small research project.

Don't make your work too narrow . If your topic is too narrow, you will not be able to expand on the ideas sufficiently and make useful conclusions. You may also struggle to find enough literature to support it.

Scope out the field before deciding your topic . This is especially important if you have a few different options and are not sure which to pick. Spend a little time researching each one to get a feel for the amount of literature that exists and any particular avenues that could be worth exploring.

Think about your future . Some topics may fit better than others with your future plans, be they for further study or employment. Becoming more expert in something that you may have to be interviewed about is never a bad thing!

Once you have an idea (or even a few), speak to your tutor. They will advise on whether it is the right sort of topic for a dissertation or independent study. They have a lot of experience and will know if it is too much to take on, has enough material to build on etc.

Developing a research question or hypothesis

Research question vs hypothesis.

First, it may be useful to explain the difference between a research question and a hypothesis. A research question is simply a question that your research will address and hopefully answer (or give an explanation of why you couldn't answer it). A hypothesis is a statement that suggests how you expect something to function or behave (and which you would test to see if it actually happens or not).

Research question examples

• How significant is league table position when students choose their university?
• What impact can a diagnosis of depression have on physical health?

Note that these are open questions - i.e. they cannot be answered with a simple 'yes' or 'no'. This is the best form of question.

Hypotheses examples

• Students primarily choose their university based on league table position.
• A diagnosis of depression can impact physical health.

Note that these are things that you can test to see if they are true or false. This makes them more definite then research questions - but you can still answer them more fully than 'no they don't' or 'yes it does'. For example, in the above examples you would look to see how relevant other factors were when choosing universities and in what ways physical health may be impacted.

For more examples of the same topic formulated as hypotheses, research questions and paper titles see those given at the bottom of this document from Oakland University: Formulation of Research Hypothesis

Which do you need?

Generally, research questions are more common in the humanities, social sciences and business, whereas hypotheses are more common in the sciences. This is not a hard rule though, talk things through with your supervisor to see which they are expecting or which they think fits best with your topic.

What makes a good research question or hypothesis?

Unless you are undertaking a systematic review as your research method, you will develop your research question  as a result of reviewing the literature on your broader topic. After all, it is only by seeing what research has already been done (or not) that you can justify the need for your question or your approach to answering it. At the end of that process, you should be able to come up with a question or hypothesis that is:

• Clear (easily understandable)
• Focused (specific not vague or huge)
• Answerable (the data is available and analysable in the time frame)
• Relevant (to your area of study)
• Significant (it is worth answering)

You can try a few out, using a table like this (yours would all be in the same discipline):

A similar, though different table is available from the University of California: What makes a good research topic?   The completed table has some supervisor comments which may also be helpful.

Ultimately, your final research question will be mutually agreed between yourself and your supervisor - but you should always bring your own ideas to the conversation.

The role of sub-questions

Your main research question will probably still be too big to answer easily. This is where sub-questions come in. They are specific, narrower questions that you can answer directly from your data.

So, looking at the question " How much do online users know and care about how their self-images can be used by Apple, Google, Microsoft and Facebook? " from the table above, the sub-questions could be:

• What rights do the terms and conditions of signing up for Apple, Google, Microsoft and Facebook accounts give those companies regarding the use of self-images?
• What proportion of users read the terms and conditions when creating accounts with these companies?
• How aware are users of the rights they are giving away regarding their self-images when creating accounts with these companies?
• How comfortable are users with giving away these rights?

Together, the answers to your sub-questions should enable you to answer the overarching research question.

How do you answer your sub-questions?

Depending on the type of dissertation/project your are undertaking, some (or all) the questions may be answered with information collected from the literature and some (or none) may be answered by analysing data directly collected as part of your primary empirical research .

In the above example, the first question would be answered by documentary analysis of the relevant terms and conditions, the second by a mixture of reviewing the literature and analysing survey responses from participants and the last two also by analysing survey responses. Different projects will require different approaches.

Some sub-questions could be answered by reviewing the literature and others from empirical study.

Formulating a Research Question or Hypothesis (Dissertations)

Research is about finding answers to questions (sometimes expressed in terms of hypotheses). It is also important to frame your research question or hypothesis as this will narrow down a broad topic of interest to a specific area of study.  

To frame your research question / hypothesis, you should take the following steps: 

Start with a broad topic that you are interested in. Use mind mapping techniques to group ideas together, organise and connect them.  

Look up current debates and topical issues to identify gaps in knowledge.  

Try coming up with potential research questions by narrowing down your topic. You can develop these questions by either challenging the view of others or attempting to fill the gaps in knowledge you have identified so far. 

Check the strength of your potential research questions / hypotheses (see below for more information).  

Hulley et al (2007) suggests using the FINER criteria to determine the strength of your research question / hypothesis.  

Ask yourself if your questions are: 

F – Feasible  Can the study be completed with the timeframe given and the resources which are available? 

I – Interesting  Is your research question / hypothesis of interest to the wider academic community? 

N – Novel  Does your research question / hypothesis promise to offer new insight into your field of study? 

E – Ethical  If you are gathering original data, would your research question / hypothesis be approved by panels and review boards? 

R – Relevant  Is your research question / hypothesis relevant to public interest or the debates currently circulating within the wider academic community? 

Research Question or Hypothesis?

Normally, in a dissertation you will have a research question OR a hypothesis.  

When to use research questions or hypotheses? 

If you use mixed methods (qualitative and quantitative) research you may need to have both hypothesis (for the quantitative part) and research question (for the qualitative part). See also the Methodology Guide .

Formulating a Research Question

We advise you to formulate a research question if  

Your project is exploratory, meaning you are not looking for a specific result.  

Your project method is qualitative, seeking to understand concepts, thoughts and experiences through non-numerical data.  

Characteristics of good research questions: 

Feasible : you must be able to answer it within your means (skills, time, financial means). It is better to have a thoroughly researched answer to a small question than to fail to find the answer to one which is too big or diffuse! 

Focused : deal with a single problem or issue that you can answer thoroughly. We recommend the use of one, maximum two, research question(s). 

Complex : find a topic that can be addresses in the space of your dissertation. No short yes or no answers! 

Relevant : find something relating to your course, and ideally helpful to society as well. 

Original : try to fill a gap in the knowledge.

• Research question examples Examples of poor research questions, and of how to rewrite them to be stronger.

Formulating a Hypothesis

A hypothesis is a reasoned, provisional statement capable of being empirically tested. As a statement, it predicts what you think the outcome of the study will be. A hypothesis is generally associated with quantitative studies (studies based on numerical data).  

Characteristics of good hypotheses: 

Testable : the hypothesis has to be capable of being proved or disproved by testing. 

Informed : make sure you take into consideration existing knowledge and experiments.  

Simple : try to make your hypothesis as simple as possible. Usually, it will be a hypothesis that shows the relationship between two variables where one is called the independent variable or ‘cause’ and the other is the dependent variable or ‘effect’.

Devising Your Research Methods

Once you have decided on your research question or hypothesis, you can start to think about your research methods. The method is the way you will provide an answer to your research question, or test your hypothesis.  

Are you going to use literature (secondary sources) only? Or are you going to use primary sources too? If so, existing data (secondary data, e.g. statistics, company data) or data you’ll find yourself (primary data, e.g. interviews, questionnaires, experiments)? Is the research going to be qualitative or quantitative? Will you need ethical clearance? 

To get started on devising your methodology you might want to have a look at the research methods others have used. When considering which methods to use, ask yourself: 

Is this a good method? 

What makes it a good method? 

Why did the researchers choose this method? 

Are there any limitations? 

Were any factors not considered? 

Were there any biases? 

Why would this work/not work for my research? 

Can I improve this method in any way?

What is and How to Write a Good Hypothesis in Research?

• 4 minute read
• 332.7K views

Table of Contents

One of the most important aspects of conducting research is constructing a strong hypothesis. But what makes a hypothesis in research effective? In this article, we’ll look at the difference between a hypothesis and a research question, as well as the elements of a good hypothesis in research. We’ll also include some examples of effective hypotheses, and what pitfalls to avoid.

What is a Hypothesis in Research?

Simply put, a hypothesis is a research question that also includes the predicted or expected result of the research. Without a hypothesis, there can be no basis for a scientific or research experiment. As such, it is critical that you carefully construct your hypothesis by being deliberate and thorough, even before you set pen to paper. Unless your hypothesis is clearly and carefully constructed, any flaw can have an adverse, and even grave, effect on the quality of your experiment and its subsequent results.

Research Question vs Hypothesis

It’s easy to confuse research questions with hypotheses, and vice versa. While they’re both critical to the Scientific Method, they have very specific differences. Primarily, a research question, just like a hypothesis, is focused and concise. But a hypothesis includes a prediction based on the proposed research, and is designed to forecast the relationship of and between two (or more) variables. Research questions are open-ended, and invite debate and discussion, while hypotheses are closed, e.g. “The relationship between A and B will be C.”

A hypothesis is generally used if your research topic is fairly well established, and you are relatively certain about the relationship between the variables that will be presented in your research. Since a hypothesis is ideally suited for experimental studies, it will, by its very existence, affect the design of your experiment. The research question is typically used for new topics that have not yet been researched extensively. Here, the relationship between different variables is less known. There is no prediction made, but there may be variables explored. The research question can be casual in nature, simply trying to understand if a relationship even exists, descriptive or comparative.

How to Write Hypothesis in Research

Writing an effective hypothesis starts before you even begin to type. Like any task, preparation is key, so you start first by conducting research yourself, and reading all you can about the topic that you plan to research. From there, you’ll gain the knowledge you need to understand where your focus within the topic will lie.

Remember that a hypothesis is a prediction of the relationship that exists between two or more variables. Your job is to write a hypothesis, and design the research, to “prove” whether or not your prediction is correct. A common pitfall is to use judgments that are subjective and inappropriate for the construction of a hypothesis. It’s important to keep the focus and language of your hypothesis objective.

An effective hypothesis in research is clearly and concisely written, and any terms or definitions clarified and defined. Specific language must also be used to avoid any generalities or assumptions.

Use the following points as a checklist to evaluate the effectiveness of your research hypothesis:

• Predicts the relationship and outcome
• Simple and concise – avoid wordiness
• Clear with no ambiguity or assumptions about the readers’ knowledge
• Observable and testable results
• Relevant and specific to the research question or problem

Research Hypothesis Example

Perhaps the best way to evaluate whether or not your hypothesis is effective is to compare it to those of your colleagues in the field. There is no need to reinvent the wheel when it comes to writing a powerful research hypothesis. As you’re reading and preparing your hypothesis, you’ll also read other hypotheses. These can help guide you on what works, and what doesn’t, when it comes to writing a strong research hypothesis.

Here are a few generic examples to get you started.

Eating an apple each day, after the age of 60, will result in a reduction of frequency of physician visits.

Budget airlines are more likely to receive more customer complaints. A budget airline is defined as an airline that offers lower fares and fewer amenities than a traditional full-service airline. (Note that the term “budget airline” is included in the hypothesis.

Workplaces that offer flexible working hours report higher levels of employee job satisfaction than workplaces with fixed hours.

Each of the above examples are specific, observable and measurable, and the statement of prediction can be verified or shown to be false by utilizing standard experimental practices. It should be noted, however, that often your hypothesis will change as your research progresses.

Understanding the Fundamentals of Research Questions and Hypotheses

Defining research questions.

Research questions are the backbone of any scholarly inquiry, guiding you through the exploration of your chosen topic. They help you focus your study and determine the direction of your research. A well-crafted research question should be clear, focused, and answerable within the constraints of your study.

Characteristics of a Strong Hypothesis

A strong hypothesis provides a specific, testable prediction about the expected outcomes of your research. It is not merely a guess but is grounded in existing literature and theory. To develop a robust hypothesis, consider the variables involved and ensure that it is feasible to test them within your study's design.

Interrelation Between Research Questions and Hypotheses

Understanding the interrelation between research questions and hypotheses is crucial for structuring your research effectively. Your hypothesis should directly address the gap in the literature highlighted by your research question, providing a clear pathway for investigation. This alignment ensures that your study can contribute valuable insights to your field.

Crafting Effective Research Questions

Identifying the purpose.

To craft an effective research question , you must first identify the purpose of your study. This involves understanding what you aim to discover or elucidate through your research. Ask yourself what the core of your inquiry is and what outcomes you hope to achieve. This clarity will guide your entire research process, ensuring that your question is not only relevant but also deeply rooted in your specific academic or practical goals.

Scope and Limitations

It's crucial to define the scope and limitations of your research early on. This helps in setting realistic boundaries and expectations for your study. Consider factors such as time, resources, and the breadth of the subject area. Narrowing down your focus to a manageable scope can prevent the common pitfall of an overly broad or vague question, which can dilute the impact of your findings.

Formulating Questions that Drive Inquiry

The final step in crafting your research question is formulating it in a way that drives inquiry. This means your question should be clear, concise, and structured to prompt detailed investigation and critical analysis. It should challenge existing knowledge and push the boundaries of what is already known. Utilizing strategies like the Thesis Dialogue Blueprint or the Research Proposal Compass can be instrumental in refining your question to ensure it is both innovative and feasible.

Developing Hypotheses in Research

From research questions to hypotheses.

When you transition from research questions to hypotheses, you are essentially moving from what you want to know to what you predict will happen. This shift involves formulating a specific, testable prediction that directly stems from your initial question. Ensure your hypothesis is directly linked to and derived from your research question to maintain a coherent research strategy.

Types of Hypotheses

There are several types of hypotheses you might encounter, including simple, complex, directional, nondirectional, associative, causal, null, and alternative. Each type serves a different purpose and is chosen based on the specifics of the research question and the nature of the study. For instance, a null hypothesis might be used to test the effectiveness of a new teaching method compared to the standard.

Testing and Refining Hypotheses

Testing your hypothesis is a critical step in the research process. This phase involves collecting data, conducting experiments, or utilizing other research methods to determine the validity of your hypothesis. After testing, you may find that your hypothesis needs refining or even reformation based on the outcomes. This iterative process is essential for narrowing down the most accurate explanation or prediction for your research question.

Examples of Research Questions in Various Disciplines

Humanities and social sciences.

In the realm of Humanities and Social Sciences, research questions often explore cultural, social, historical, or philosophical aspects. How does gender representation in 20th-century American literature reflect broader social changes? This question not only seeks to uncover specific literary trends but also ties them to societal shifts, offering a rich field for analysis.

Natural Sciences

Research questions in the Natural Sciences are typically aimed at understanding natural phenomena or solving specific scientific problems. A common question might be, What are the effects of plastic pollutants on marine biodiversity? This inquiry highlights the environmental concerns and seeks empirical data to understand the impact.

Applied Sciences

In Applied Sciences, the focus is often on improving technology or engineering solutions. A pertinent question could be, How can renewable energy sources be integrated into existing power grids? This question addresses the practical challenges and potential innovations in energy systems, crucial for advancing sustainable technologies.

Analyzing Hypothesis Examples Across Fields

Case studies in psychology.

In psychology, hypotheses often explore the causal relationships between cognitive functions and behaviors. Consider how a hypothesis might predict the impact of stress on memory recall . By examining various case studies, you can see how hypotheses are specifically tailored to address intricate psychological phenomena.

Experimental Research in Biology

Biology experiments frequently test hypotheses about physiological processes or genetic information. For instance, a hypothesis might propose that a specific gene influences plant growth rates. Through rigorous testing, these hypotheses contribute significantly to our understanding of biological systems.

Field Studies in Environmental Science

Field studies in environmental science provide a rich ground for testing hypotheses related to ecosystem dynamics and conservation strategies. A common hypothesis might explore the effects of human activity on biodiversity. These studies often involve complex data collection and analysis, highlighting the interrelation between empirical evidence and theoretical predictions.

Methodological Approaches to Formulating Hypotheses

Quantitative vs. qualitative research.

When you embark on hypothesis formulation, understanding the distinction between quantitative and qualitative research methodologies is crucial. Quantitative research focuses on numerical data and statistical analysis, ideal for hypotheses that require measurable evidence. In contrast, qualitative research delves into thematic and descriptive data, providing depth and context to hypotheses that explore behaviors, perceptions, and experiences.

The Role of Theoretical Frameworks

Theoretical frameworks serve as the backbone for developing robust hypotheses. They provide a structured way to align your hypothesis with existing knowledge. By integrating theories and models relevant to your study, you ensure that your hypothesis has a solid foundation and aligns with established academic thought.

Utilizing Existing Literature to Form Hypotheses

A thorough review of existing literature is indispensable for crafting a well-informed hypothesis. This process not only highlights gaps in current research but also allows you to build on the work of others. By synthesizing findings from previous studies, you can formulate hypotheses that are both innovative and grounded in academic precedent.

Evaluating the Impact of Well-Formed Research Questions and Hypotheses

On research outcomes.

Understanding the impact of well-formed research questions and hypotheses on research outcomes is crucial. Well-crafted questions and hypotheses serve as a framework that guides the entire research process , ensuring that the study remains focused and relevant. They help in defining the scope of the study and in identifying the variables that need to be measured, thus directly influencing the validity and reliability of the research findings.

In Academic Publishing

The role of well-defined research questions and hypotheses extends beyond the research process into the realm of academic publishing. A clear hypothesis provides a strong foundation for the research paper, enhancing its chances of acceptance in prestigious journals. The clarity and direction afforded by a solid hypothesis make the research more appealing to a scholarly audience, potentially increasing citation rates and academic recognition.

In Grant Applications

When applying for research grants, the clarity of your research questions and hypotheses can significantly impact the decision-making process of funding bodies. A well-articulated hypothesis demonstrates a clear vision and a structured approach to addressing a specific issue, which can be crucial in securing funding. Grant reviewers often look for proposals that promise substantial contributions to the field, and a strong hypothesis can be a key factor in showcasing the potential impact of your research.

What is a Hypothesis in a Dissertation?

Hypotheses play a vital role in any study. How would you define the underlying belief of a dissertation? It serves as a response to the researcher's posed research question. Derived from the examined facts, it anticipates connections among them. After analyzing the selected research issue, the researcher develops initial notions about the relationships between known facts by addressing the most significant concerns.

What are some characteristics of a dissertation hypothesis.

Here are some points to remember:

Sources that can be trusted should be included in it. It is your responsibility as an author to defend your position, so be sure you include testable assumptions and material that is available on the internet. The problem studied must be emphasized, and powerful statements should be delivered.

There should be no question about it. You should not turn a hypothesis into a rhetorical question that doesn't need an answer. Dissertation hypotheses are more positive than thesis statements since you need to research and draw conclusions.

There should not be too much complexity. It implies that your readers also understand the point if you make the dissertation hypothesis overt. Conversely, defending your position risks falling into the wordiness trap. Make a brief, precise idea that represents your concept, and check the word limit.

References and citations should be included. If there are no references, what is the point of a hypothesis? References and bibliographies that helped you make an advanced step in that area should be cited along with previous authors and problems studied earlier. Give credit to the researchers when you base your academic paper on their work.

Why is the Dissertation Hypothesis Important?

A research hypothesis is a prediction about the outcome of a study that can be tested. This includes variables and their relationships as well as aspects such as the population. Based on empirical evidence, it specifies the role played by each element. In conducting research, the researcher makes certain assumptions. As far as we know, the aim is to present the expected results after they are tested.

• This ensures the validity and scientific integrity of the entire research process.
• The probability of failure and progress in research can be assumed.
• As a result, it helps connect the underlying theory and the specific research question .
• In addition, it assists in data analysis and measures research validity and reliability.
• It proves the validity of the research by providing a basis or evidence.
• In contrast to theoretical descriptions, it helps to describe research studies in concrete terms.

Main Sources of Hypothesis

• Theoretical science.
• Observations based on previous studies and current experiences.
• Similarities between different phenomena.
• A general pattern of thinking that affects people.

What are Some of the Types of Hypotheses?

Understanding the concept of hypotheses completely is essential for creating a good hypothesis. It is, therefore, important to understand the different types of hypotheses before you begin writing.

Regarding types, there are mainly two, namely Alternative and Null hypotheses.

1. Alternative Hypothesis

Academically, it is often referred to as H1. Identifying the expected outcome of your research procedure is the purpose of this type of research. Furthermore, it can be further classified into two subcategories:

The first is directional: This statement specifies how to gather the expected results. In most cases, it is used to establish a relationship between variables rather than to compare multiple groups. 

Example : The performance of athletes on the field will be improved by attending physiotherapy sessions.

Another alternative hypothesis is non-directional: As the name implies, a non-directional alternative hypothesis does not suggest a direction for the expected outcomes.

Example : Attending physiotherapy sessions affects an athlete's performance on the field.

Observe carefully the two statements in the above examples. A directional statement states that physiotherapy sessions will enhance or boost performance. Non-directional statements establish a correlation between the two variables (physiotherapy sessions and performance). There is no indication, however, that physiotherapy sessions will result in better or worse performance.

2. Null Hypothesis

H0 is the null hypothesis. As opposed to an alternative hypothesis, there is a null hypothesis. This is a statement that defines the opposite of what you expect to see during your research. Essentially, a null hypothesis asserts no relationship exists between the variables specified in the hypothesis.

The last example can be stated as follows to provide an idea of how a null hypothesis is written:

Example: On-field performance is not affected by physiotherapy sessions.

Alternative and null hypotheses are written to clarify and examine the research problem in detail. A research problem statement is a question that is not valid or testable, while a hypothesis is a hypothesis that can be tested. The former, however, can be tested, validated, or denied.

3. Simple Hypothesis

Statements that reflect the relationship between dependent and independent variables are called dependent statements. You will understand the example if you follow it through,

• Lung cancer is a common result of smoking
• Obesity may result from sugar-rich diets

4. Complex Hypothesis

Depending on the research problem, complex hypotheses imply a relationship between several dependent variables. You can better understand this by following the examples below:

• A person who eats more fruits tends to have a higher immunity, a lower cholesterol level, and a higher metabolic rate.
• Work hours can be made more productive by taking short breaks during them.

5. Empirical Hypothesis

A "Working Hypothesis" is also known as an experiment that validates a theory. As a result, the statement appears plausible and not just a wild guess.

In order to learn how to create an empirical hypothesis, here are a few examples:

• Anaemia is less likely to occur in people who take iron tablets than in ones who take vitamin B12.
• Giving food immediately after obedience to a command helps dogs learn faster.

6. Statistical Hypothesis

The statistical hypothesis is a statement claiming an explanation based on a sample of the population. An example of logic-based analysis is researching a particular population and gathering evidence using a certain sample size.

The following are some hypothetical statistical statements to help you understand how your research can be conducted by leveraging statistical data:

• 54% of Canadians are between the ages of 22 and 27
• An Agro-based industry in Kenya employs 57% of the rural population.

Hypothesis VS Prediction: How Do They Differ?

Hypotheses can mean predictions, too, causing confusion. Both are guesses but different. Hypotheses are for science; predictions are more common outside of science. A hypothesis is like a smart guess. It uses what we've learned to understand things we're unsure about. It connects facts to make an educated scientific guess. Experiments test these guesses. Assumptions are what you think will happen in the study.

Predictions are different. They're often just guesses without proof. While they could be scientific in theory, they usually lack facts. Predictions guess what might happen, often by people who don't know much. Also, how we prove these is very different. Predictions have only one test: if they're right or wrong when the event happens. Hypotheses can be tested many times by different scientists using various methods.

The following examples will help you better understand the difference between a hypothesis and a prediction:

Example Hypothesis: Eating more fruits and vegetables will lead to faster weight loss and a cleaner body.

The hypothesis is based on general knowledge (i.e. fruits and vegetables have fewer calories than other foods) and past experiences (i.e. people who choose healthier foods like fruits and vegetables lose more weight). Though it is still a guess, it is based on facts and can be tested.

Example Prediction: 2023 will be the end of the world.

A prediction foretells what will happen in the future. However, given the lack of actual grounded evidence to support this claim, it is a fictional assumption.

How to Develop a Hypothesis?

It is not easy to select a hypothesis. Let us suppose you have chosen an intriguing topic with lots of research potential. It may be difficult for you to choose a dissertation hypothesis in this case. When you have multiple exploration sources, it can be challenging to determine the hypothesis. These dissertation hypothesis writing guidelines/steps can help you improve the quality of your hypothesis part.

1. Conducting Research is the First Step

Before creating a hypothesis, a person should collect considerable information. You should read as much as you can on the topic under research; you should read books and articles by scientists, experts and professionals who have examined something related to your topic. By absorbing their knowledge and experience, you will be ready to conduct your own research. Gaining new facts may enable you to analyse other scholars' thoughts objectively and even criticize them after gaining new knowledge about your problem. You are ready to conduct research when there is something that has not been investigated about your topic. Make a list of what you would like to investigate.

2. Hypothesis Generation is the Second Step

It is now time to formulate a clear hypothesis based on your research. When a student chooses a research topic, they often have an idea of what they are going to investigate. At this step, many students fail to realize the problem of their research and need time to enhance their knowledge by reading clever thoughts by famous scholars. Each student must submit a dissertation proposal with a hypothesis or approximate thesis statement to be considered for a dissertation, but a true hypothesis is only presented after thorough research is conducted. Your hypothesis will be supported by the data and evidence you collect after you complete the investigation.

3. Supporting Your Hypothesis in Step Three

Half the success lies in brainstorming good concrete hypotheses that attract the reader's attention. You will be awarded a degree when your professor recognizes that your dissertation deserves to be read. To answer this rhetorical question, you asked at the start of the dissertation, you must support your hypothesis with reliable evidence. In other words, you should support your hypothesis throughout the dissertation in order to persuade the reader. Utilize the ideas of renowned scholars and experts in your field as well as your own research.

What are Some Tips and Tricks for Writing A Good Hypothesis?

Below are some tricks and tips for your convenience:

• For a dissertation hypothesis to be effective, you will need to design an experiment that will allow the data you collect to be analyzed statistically. Hypothesis testing begins with this step. It is possible to reject either type of hypothesis through statistical analysis. As the student, you will have to refine or redesign the research hypothesis if it is rejected.
• When formulating your dissertation hypothesis, conduct thorough research. Do not assume that your alternative and null hypotheses are true out of the blue. You have to believe them to be true. An effective dissertation hypothesis can be backed up by literature and research.
• The hypothesis should be simple enough for the reader to understand. As a writer, if your hypotheses are complicated, it can be hard to explain your ideas well. Know how many words you're expected to use for your hypothesis, and once you've got that, make sure it's short and to the point.
• Always make sure that the hypothesis is related to your paper's aims and objectives. This is crucial if you are making a vague or ambiguous claim. Moreover, the hypothesis should be linked with your research questions; through it, your readers should be able to get a clear sense of what you are trying to convey. You will be able to establish this relationship pretty well if you get dissertation help from a professional writer. In case you are too worried: do not be because you have firm support to rely on since we are experts at providing dissertation writing assistance.
• Remember that citations and references should also be included. In order to give credit where it is due, you should cite any work you used to develop your ideas.

Frequently asked questions

Should i use a research question, hypothesis, or thesis statement.

The way you present your research problem in your introduction varies depending on the nature of your research paper . A research paper that presents a sustained argument will usually encapsulate this argument in a thesis statement .

A research paper designed to present the results of empirical research tends to present a research question that it seeks to answer. It may also include a hypothesis —a prediction that will be confirmed or disproved by your research.

Frequently asked questions: Writing a research paper

A research project is an academic, scientific, or professional undertaking to answer a research question . Research projects can take many forms, such as qualitative or quantitative , descriptive , longitudinal , experimental , or correlational . What kind of research approach you choose will depend on your topic.

The best way to remember the difference between a research plan and a research proposal is that they have fundamentally different audiences. A research plan helps you, the researcher, organize your thoughts. On the other hand, a dissertation proposal or research proposal aims to convince others (e.g., a supervisor, a funding body, or a dissertation committee) that your research topic is relevant and worthy of being conducted.

Formulating a main research question can be a difficult task. Overall, your question should contribute to solving the problem that you have defined in your problem statement .

However, it should also fulfill criteria in three main areas:

• Researchability
• Feasibility and specificity
• Relevance and originality

Research questions anchor your whole project, so it’s important to spend some time refining them.

In general, they should be:

• Focused and researchable
• Answerable using credible sources
• Complex and arguable
• Feasible and specific
• Relevant and original

All research questions should be:

• Focused on a single problem or issue
• Researchable using primary and/or secondary sources
• Feasible to answer within the timeframe and practical constraints
• Specific enough to answer thoroughly
• Complex enough to develop the answer over the space of a paper or thesis
• Relevant to your field of study and/or society more broadly

A research aim is a broad statement indicating the general purpose of your research project. It should appear in your introduction at the end of your problem statement , before your research objectives.

Research objectives are more specific than your research aim. They indicate the specific ways you’ll address the overarching aim.

Once you’ve decided on your research objectives , you need to explain them in your paper, at the end of your problem statement .

Keep your research objectives clear and concise, and use appropriate verbs to accurately convey the work that you will carry out for each one.

I will compare …

Your research objectives indicate how you’ll try to address your research problem and should be specific:

Research objectives describe what you intend your research project to accomplish.

They summarize the approach and purpose of the project and help to focus your research.

Your objectives should appear in the introduction of your research paper , at the end of your problem statement .

The main guidelines for formatting a paper in Chicago style are to:

• Use a standard font like 12 pt Times New Roman
• Use 1 inch margins or larger
• Apply double line spacing
• Indent every new paragraph ½ inch
• Include a title page
• Place page numbers in the top right or bottom center
• Cite your sources with author-date citations or Chicago footnotes
• Include a bibliography or reference list

To automatically generate accurate Chicago references, you can use Scribbr’s free Chicago reference generator .

The main guidelines for formatting a paper in MLA style are as follows:

• Use an easily readable font like 12 pt Times New Roman
• Set 1 inch page margins
• Include a four-line MLA heading on the first page
• Center the paper’s title
• Use title case capitalization for headings
• Cite your sources with MLA in-text citations
• List all sources cited on a Works Cited page at the end

To format a paper in APA Style , follow these guidelines:

• Use a standard font like 12 pt Times New Roman or 11 pt Arial
• If submitting for publication, insert a running head on every page
• Apply APA heading styles
• Cite your sources with APA in-text citations
• List all sources cited on a reference page at the end

No, it’s not appropriate to present new arguments or evidence in the conclusion . While you might be tempted to save a striking argument for last, research papers follow a more formal structure than this.

All your findings and arguments should be presented in the body of the text (more specifically in the results and discussion sections if you are following a scientific structure). The conclusion is meant to summarize and reflect on the evidence and arguments you have already presented, not introduce new ones.

The conclusion of a research paper has several key elements you should make sure to include:

• A restatement of the research problem
• A summary of your key arguments and/or findings
• A short discussion of the implications of your research

Don’t feel that you have to write the introduction first. The introduction is often one of the last parts of the research paper you’ll write, along with the conclusion.

This is because it can be easier to introduce your paper once you’ve already written the body ; you may not have the clearest idea of your arguments until you’ve written them, and things can change during the writing process .

The introduction of a research paper includes several key elements:

• A hook to catch the reader’s interest
• Relevant background on the topic
• Details of your research problem

and your problem statement

• A thesis statement or research question
• Sometimes an overview of the paper

How to Write a Hypothesis for a Dissertation

Types of hypotheses.

When writing a dissertation , it is common practice to develop a hypothesis based on the research a writer has undertaken. A hypothesis often predicts some type of relationship and it usually takes the form of a “research” or an “alternative” hypothesis. For the purpose of balancing the findings of a piece of research work, it is also necessary to create another type of hypothesis – a “null” one. This latter type serves the purpose of claiming the non-existence of a predicted relationship in a “research” hypothesis. Experts say that, when directly tested, the null hypothesis does not predict any effect, and the “alternative” hypothesis contradicts the former by predicting an effect. Additionally, the “research” type of hypothesis can take different forms. A knowledge base entitled Research Methods indicates there are “one-tailed” and “two-tailed” research hypotheses where, respectively, the first type specifies a particular direction (e.g., an increasing direction or a decreasing direction) and the second type specifies a change only rather than a direction. 

Writing a Hypothesis

A hypothesis should be written before data is collected and analyzed. An effective hypothesis should be capable of being tested and should include a variable of the independent variety, which the writer controls. It should also have a variable of the dependent variety, which is measured or observed against the independent type. Say, for instance, you take as your independent variable the way the media reports on violence and the dependent variable as aggression. In this case, your “null” hypothesis might state that, “the way the media reports on violence does not affect aggression.” Therefore, your “alternative” hypothesis might state that, “the way the media reports on violence does affect aggression.” Likewise, to develop a “one-tailed” hypothesis, you may well state that, “the way the media reports on violence leads to an increase in aggression.” However, in all cases, it is important to ensure statements are short and to-the point. Additionally, you should keep the results that will be measured later on in your project in mind.

Hypothesis is important when your work should determine whether a certain prediction regarding the relation between variables is right. Oftentimes, they are presented in a form of sub-questions. Find out everything about writing a hypothesis.

Hypothesis Sample

Freshmen attend lecture more often than sophomores.

How to Use Hypotheses in a Dissertation?

It is significant to remember the following things when your dissertation contains hypotheses:

• Hypothesis cannot be the main question.

The main question is the research question. Do not confuse it with hypothesis. Hypotheses can be presented in a form of sub-questions.

• Preliminary research should be conducted.

When writing a hypothesis, you should understand that its task is state what you believe is true. Prior to stating anything, a research should be conducted. Pay attention to literature and problem statement.

• Conceptual framework should be created.

Your research should be used as the basis that helps to create a conceptual framework. Here you need to show what you need to find while conducting a real investigation.

• Form the hypotheses.

It is time for writing a hypothesis. You need to discuss each hypothesis in separate sections of your dissertation.

• It is important to test the selected hypotheses.

Test the hypotheses to find out whether your expectations are right. In case they are not right, you cannot verify your hypotheses.

It is important to create null and alternative hypotheses. They will assist you to facilitate the testing. Below find samples of null H0 and alternative H1 hypotheses. They will help you to find out how to make a hypothesis

Hypothesis Testing

Dissertation experts say that both the null and research types of hypotheses should be tested against all possible outcomes so that only one is acceptable at the end of the process. This would mean rejecting the other. When all data is analyzed, you should be able to decide whether to accept the “alternative” hypothesis and reject (or not) the “null” hypothesis.

Finding Example Hypotheses

It is usual practice to test a number of different hypotheses in the course of completing a dissertation project. Much depends on the topic and discipline and the writer’s focus. One student, for instance, gave her dissertation the same title as her hypothesis, e.g., “Do Leadership Styles Differ at National, State, and Local Level among Those who Advocate on Behalf of Disabled People.” The independent variable in the student’s hypothesis concerned leadership and the dependent variable was those who advocate on behalf of disabled people. If you just look through a number of the dissertation titles published in any given year by a university or college, you should find plenty examples of different hypotheses and get ideas on ways to present these.

How To Write A Hypothesis Guide And Detailed Instructions

Whether you’re studying for a college degree, MBA, or Ph.D., developing a hypothesis for your research is mandatory. You must know how to write a good hypothesis to impress your professors. Now, how should a hypothesis be written?

This is where some students get confused and exhausted. You already know that you’re to formulate a hypothesis around something testable. But you don’t know how to create hypotheses based on previous observations that you would later explain in your paper or journal.

In this article, you’ll learn what a hypothesis is, how to make a hypothesis, examples of how to write hypothesis statement, and how to go about yours.

What Is A Hypothesis?

A hypothesis is a statement that is not proven, and it’s an assumption that you’ll base your research on. They must be testable: they must have answers that can be checked with experiments and evidence.

The theory around your hypothesis becomes valid when it’s proven to be true through experiments. Scientists have rules for writing that make their chemistry, physics, and biology research reproducible.

An essential part is that they must understand the experiments of others so that they can build on them and improve them. These rules define how scientists write about science. This rule applies to hypotheses, too.

Why Do You Need A Hypothesis?

Writing a good hypothesis is a key part of any scientific exploration. It allows a broad and open-ended question that compels you to investigate. There are many other reasons, including:

It’s different from a theory because a theory is something like:

“The earth orbits around the sun.”

This is not testable because we know that it’s true. A theory is more like an explanation for why something happens, while a hypothesis is a guess about what will happen and why it would.

A hypothesis is a statement of the relationship you’ve observed in a pair of variables. The easiest way to think about it is that the hypothesis is your testable statement for your research project.

You would typically use your background knowledge and experience as a researcher to come up with this statement before you set out to collect data. A good hypothesis will give you insight into what kind of data you need to collect to answer the question (or provide evidence).

For example:

“People who live in cities have higher stress levels than those who live in rural areas because there are more people around them all day long!”

This hypothesis would then lead us to ask questions like “How do we measure stress?” or “What factors contribute to stress?” You’ll provide answers to these questions with the paper.

A hypothesis can be proven or disproven throughout an experiment. The most common way to disprove a hypothesis is through statistical significance testing. This entails using probability and data analysis to show that there’s no practical difference between the two compared groups.

The hypothesis is a testable statement about how the world works. It’s also a way to properly arrange and structure your data. Without a hypothesis, you won’t even know what to set your scientific experiment on. A hypothesis is what you’ll use to predict what will happen in the future, and the data you collect during the research will help validate or disprove this.

In science, you’re always trying to figure out why things happen the way they do and what factors affect them. When you know how something works, “why do some people get sick while others don’t?” You might make up a hypothesis to test your idea: “People who are exposed to germs get flu symptoms.” Here’s how to start a hypothesis as the answer lets you determine whether your idea is right or wrong; an experiment then validates (or disproves) it.

Now that you know why you need to formulate a testable hypothesis, learn how to write a research hypothesis with tangible examples.

How To Write A Hypothesis

Before you start your experiments in the lab, it’s important to take some time to think about what you’re trying to achieve. After all, you can’t know your research destination until you plan it beforehand. This is why mastering how to state a hypothesis gives room for healthy predictions. Here’s how you formulate hypothesis:

Your first step is to determine what you want to investigate. You can start with a question you’d like to answer or a problem that needs solving.For example, if you’re a teacher trying to improve your students’ reading skills, you might ask:

“What techniques can I use for my students to boost reading comprehension scores on their standardized tests?”

This could also be stated as “Do test-taking strategies lead to improved standardized test scores?”

Once your question pops in your mind, especially while reflecting on a scientific paper you’ve read or a documentary you saw, write it down and commence research.

You need some facts to state a hypothesis and prove it. It might be tricky to get these facts, and you’ll want to look for relevant and irrelevant information.

Relevant information is directly related to your hypothesis. For example, your relevant sources would be academic, examination, and psychology journals, quantitative data or news outlets for the above statement.

Irrelevant information is any other kind of data, and this could be random news outlets or interviews that could help bolster what your assumptions are.

Use the word “because” to indicate that your variable causes or explains another variable. For example: If we are testing whether exercise leads to weight loss, our sentence might look like this:

“Consistent gym practice causes weight loss because it burns calories and gets the body in shape.”

You need to identify if your hypothesis is testable or if it’s an opinion you can’t prove. You can’t test what you don’t know or can’t prove. So you’d need to rewrite your hypothesis if you think it’s not testable.

Your hypothesis should be clear, concise, testable, specific, and relevant. The best way to do this is to write a brief summary of your hypothesis in the form: “If X happens, then Y will happen.”

Here’s a sample hypothesis:

“If I add 15 minutes to my sitting time everyday, then my body mass index (BMI) will reduce by 5 points in three months.”

Now that you’ve defined your idea, it’s time for the actual experiment to determine whether it’ll work.

How To Write A Hypothesis Statement: Example Of A Hypothesis

There are numerous examples of a hypothesis statement you can take a clue from. A scientific hypothesis examines two variables that need evidence-based research to be considered valid. For example:

“If I increase the amount of water applied to a plant garden, then it will make it grow faster.”

You have identified the independent and dependent variables in this statement. The independent variable is “amount of water applied,” and the dependent variable is “grow faster.” You also included a control group, which is important in scientific experiments to eliminate bias from other factors that could influence your results.

In this case, you are comparing how much growth there would be if you increase the amount of water versus how much growth there would be if you do not increase it.

You then need to research the topic in detail and design an experiment before you can write your report. The first step is to decide what you’re going to measure, how you’ll measure it, and how many times you’ll do this so that it’s accurate.

Once you’ve measured your experiment, interpreting the results can be challenging. You should look at graphs or charts of your data to see if any patterns or trends might indicate a cause-and-effect relationship between two things (like applying more water to the plant garden and faster growth).

After looking at the results of your experiment and deciding whether or not they support your original hypothesis, use this new knowledge in your conclusion. Write up something like:

“Based on my findings, it’s clear that applying more water to any plant garden would make the plant garden grow faster and greener.”

Then, write an introduction section where you can explain why this project interests/matters/is relevant to your reader. At this point, your hypothesis is no longer an educated guess. It started as one (with the observation or thoughts/idea) and ended as verifiable.

Format For Hypothesis: How Should A Hypothesis Be Written?

The usual format of a hypothesis is If – (then) – because.

Because we have the idea that if a hypothesis is formatted as an if-then statement, it’s clear what the hypothesis is about. This can be helpful for your readers and yourself if you ever need to come back and look at your work.

So, now that you know how to format it correctly (and why) let’s look at some hypothesis examples.

“If snow falls, then I’ll catch a cold when I get outside because cold can be a result of heavy snow.”

“If anyone in my family eats cake, then we will feel sick because the cake contains ingredients we are allergic to.”

“Some grasses never grow because they’re stumped every day.”

All these show that two variables must come together in the sentence. The variables must also be a probability the research attempts to solve to make them valid statements.

How To Know Your Hypothesis Is Good

Now that you know how to create a hypothesis, you need to know if it’s good through these pointers:

State a Hypothesis as Clearly as Possible You can choose precise words that are neither ambiguous nor too technical. You should also avoid jargon and words with multiple meanings to keep your language simple and clear. Don’t use fancy or pretentious words unless they’re absolutely necessary for the meaning you want to convey, and make sure you’ve used them in their correct context. In addition, use a tone of voice appropriate to the audience. A scientific paper may need more formal language than an article for popular consumption. A Good Hypothesis Should Explain the Bond Between Multiple Variables The main purpose of forming a hypothesis is to explain the relationship between multiple variables clearly. The relationship should be testable for it to be proven. This is, why if X leads to Y, what is in between that connects X and Y? This must reflect in the hypothesis as it’s the factor that’ll be experimented. A Hypothesis should Be Testable This means that your hypothesis should be a statement that can be proven or disproven with an experiment. You want to make sure your hypothesis is specific enough to guide you towards the right experiment but not so specific that it eliminates any other possible outcomes of your experiment. Also, a hypothesis should not make claims about unobservable things (like feelings or thoughts). Instead, focus on observable results (things we can see) like measurements and observations from experiments conducted by scientists over time.If your hypothesis isn’t testable, then it needs to be reformulated.

What Should You Do If Your Hypothesis Is Incorrect?

You need to reformulate your thesis if it’s incorrect. You may have to reevaluate the problem or look at it differently. It’s also possible that you need to test your hypothesis with a different method of experimentation.

Here are some ideas from the best scientific thesis writing help experts:

Try Another Approach: Try looking at your hypothesis from a different angle, or consider changing up your methods entirely (for example, instead of asking people what they think will happen in the future and then testing their opinions against reality, you could run an experiment where participants predict events and then actually follow up on those predictions). Share Your Idea with a Third Party: Your hypothesis can be tested by allowing a third party to observe the results of your attempt to prove or disprove the statement. For example, if you’re testing whether peanuts can be made into peanut butter using only as few steps as possible, have someone else make it for you or observe them make it.

Document how you made your product and recorded any necessary changes along the way. This will help you know what works and doesn’t so that you’ll make changes to the whole idea.

What Does a Dissertation Hypothesis Mean?

By: Tasha Kolesnikova

The hypothesis in a dissertation is part of the introduction to student work. It is located after the goal with objectives and before research methods. Despite its modest volume, this element's development is significant, since it is the mainstay of the entire study, its driving force. The thesis is created to confirm or refute the formulated hypothesis in the process of research.

What Are Variables In Hypothesis For?

What is the significance of a hypothesis in a dissertation, the special importance of writing a hypothesis, the null hypothesis, the nondirectional hypothesis, the directional hypothesis, ask a question to dissertation, explore sources of information, create your hypothesis, check if you created the hypothesis correctly, use three ways to formulate your hypothesis, create a null hypothesis, where to get sources to form a hypothesis.

Scientists argue that a hypothesis is like a predicted result, an assumption, the reliability of which is verified empirically in the course of work. For the sake of confirming or refuting it, you choose bibliographic sources, perform theoretical and practical research, and formalize your paper. At the end of the project, you assess whether the guess put forward corresponds to the truth. If so, then it will become the theory that you have proven with your work. If not, it is rejected because refutation is also a valuable conclusion.

Dissertation Hypothesis - What is It?

You cannot solve a problem without outlining ways to resolve it. We can find ways to solve a problem only if we admit the fact of possibility or impossibility. That is, to fix the problem, it is necessary to assume or allow something. This will be your hypothesis, which you need to prove or disprove.

A variable is an empirical quality, a sign of a phenomenon that can take on more than one value. Variables can be both qualitative and quantitative. Using variables, you can confirm or disprove a hypothesis. Depending on the goals set, the variables are divided into dependent, independent, and interfering.

Independent ones are variables that characterize influencing conditions, factors, circumstances. The dependent variable is the changeable quality of the study object, which is considered a consequence of the independent variable's action. The assumption determines the relationship of dependence and independence of variables.

Whether a variable is dependent or independent is determined by the hypothesis's relationship, which contains the variable. The same variable may be dependent on one study and independent in another. For example, a researcher, observing the lobbying struggle of interest groups, could conclude that the more organized groups with specific interests in the state, the higher the government spending on social security programs. In this case, the number of groups is the independent variable, and the level of expenditure is the dependent variable.

The hypothesis sets the direction for all research and determines the scientific significance of all work. It is written in the introduction. The assumption takes no more than one paragraph. In writing a dissertation, the author selects the necessary material, conducts particular research, gives a specific structure to work, and decides how to write a conclusion , based on the assumption.

The student's facts in the main part of the document act as evidence for the hypothesis of theoretical work. If we are talking about practical work, then points are played by the documented results of experiments and experiments, certain calculations, and research.

To understand if your hypothesis is correct, check it for the following attributes:

• there are no controversial concepts in the formulation that in themselves can become the topic of some other research;
• the ability to test statements using empirical or theoretical methods;
• relevance and connection with the stated problem;
• cognitive value and effectiveness;
• practical benefits for the follow-up research program.

If all this is characteristic of your assumption, then it is well written. But the main thing that should be different is the ability to test it with the thesis. Just determine whether you need to prove your statement. If yes, then the proposal was successful.

One might say a hypothesis is the same research tool as a microscope, oscilloscope, or centrifuge. But each device has its specificity and, accordingly, its area of application, its range of tasks.

The microscope is designed to study tiny objects; the oscilloscope is for studying fast processes; the centrifuge is for looking for substances that differ in density. Hypotheses have a different purpose. They make it possible to move from a head-on study of an intractable problem to the course of the consequences of an assumption, which, as a rule, refer to other, often more studied, branches of science. In other words, the hypotheses put forward in solving difficult problems are designed to transfer research from an area that is somehow inconvenient to study to another, more convenient area.

There Are Three Types Of Hypothesis

A specific form of scientific foresight is a hypothesis. After defining the object and subject, goals, and objectives of the research, in the development of experimental work and its comprehension, one continually returns to the assumption as the research work's reference point.

At the same time, this is the assumption of the relationship in which the studied phenomenon is with others, its internal structure, essence, driving forces, etc. The advancement of a hypothesis is a way to discover connections between phenomena. An assumption as a means of transition from old knowledge to new inevitably comes into conflict with existing ideas. In the form of a assumption, there is a real movement of knowledge towards new, more profound, generalizations towards disclosing the laws of regularities, principles, etc. Therefore, you need to investigate three types of hypotheses:

• The null hypothesis;
• The nondirectional hypothesis;
• The directional hypothesis.

The word "zero" comes from the Latin word nullus, which means "nothing." Perhaps this definition is useful for a complete understanding of an often uncertain term. Your null hypothesis is that nothing will change or improve between the two sets of data during testing. This is not what you want to prove, but instead what you want to refute.

Let's go straight to an example to understand how the null hypothesis is formed. For example, when a scientist wants to find a link between smoking and lung cancer, it is not enough to find one smoker with lung cancer. A significant amount of data must be collected and analyzed before this scientist can argue a relationship between smoking and lung cancer. In this kind of research, the null hypothesis plays a key role.

The null hypothesis is essentially the assumption that the outcome the ultimate goal of any research does not exist. As far as your search for a relationship between smoking and lung cancer goes, the null hypothesis will say no such relationship exists. The question is, at what point will the data collected be sufficient to override this claim.

If we talk about smoking and lung cancer, then the null hypothesis rules out long ago: no self-respecting scientist will resort to it now. But there was a time when there was not enough data to rule it out, and the researchers could not prove that the incidence of lung cancer among smokers and nonsmokers was not just a matter of chance. Only having a large amount of data and reducing the possibility of a random result to a minimum can the null hypothesis be ruled out.

Along with the null hypothesis, the researcher usually formulates the so-called alternative assumption I - the statement that he will consider accurate if he rejects R0. When considering some hypotheses, I's formulation is obvious, and it is not worth talking about an alternative assumption. For example, this applies to the assumption of the absence of a connection, which scientists tested using the x2 criterion. It is opposed by the only possible alternative hypothesis, which states a connection between the variables. This alternative hypothesis is called the nondirectional assumption.

And so you should know that nondirectional hypothesis means that we prove that phenomena, situations, laws are authentically different, but we do not prove by what exactly. However, the nondirectional hypothesis states that there is a relationship or difference between variables. Hypotheses formulate if it is necessary to establish only differences in the form or values of the features' distribution.

Directional hypotheses are put forward if the value of an indicator in one population is higher than in another; if, under the influence of some actions, more pronounced changes occur in one set than in another.

The directional hypothesis formulates when the researcher assumes the presence or absence of differences in a specific direction: the experimental group exceeds or does not exceed the control one by some indicator. The directional hypothesis records only the presence-absence of differences, without indicating their direction: the experimental group differs from the control group or does not differ.

Hypothesis Development Process

As a stage in the research process, the development of an assumption often uses, which can be an effective means of finding ways to solve a problem and understanding it. A hypothesis is a process of developing thought. Of course, it is impossible to give a general model for constructing an assumption for all life cases. This is because the conditions for creating an assumption depend on the originality of practical activity and the problem's specifics under consideration. Nevertheless, it is possible to determine the general boundaries of the stages that the thought process goes through in an assumption.

The main stages of hypothesis development are:

• Ask a question;
• Do some preliminary research;
• Formulate your hypothesis;
• Refine your hypothesis;
• Phrase your hypothesis in three ways;
• Write a null hypothesis.

Let's consider the content and features of each stage in more detail.

To put forward a hypothesis dissertation, it is necessary to ask questions about the observed phenomenon, which would justify a particular assumption and explain the unknown. Therefore, the construction of an assumption is associated with posing questions related to the phenomenon that we are explaining and do not coincide with the existing explanation.

Based on the questions posed, an assumption is made about what the investigated phenomenon is, that is, an assumption formulates in the narrow sense of the word. The premise is made as a result of the logical processing of the collected questions. On their basis, an assumption is put forward. It is the questions that make up the main content of the hypothesis dissertation.

The questions contain the knowledge that comes as a result of the generalization of facts. They are the core of the assumption around which all cognitive and practical activity goes. The question in the hypothesis is, on the one hand, what you have to explain in the end, what you come to as a result of observation and generalization of facts. On the other hand, it is the starting point for further studying the phenomenon, indicating the path of cognition, determining how all research should go.

To understand what dissertation hypothesis to put forward in the text, it is necessary to carry out a little research on the sources of information. You need to study the bibliographic record - this is where you can get important information about the usefulness of a printed or electronic source of information. Bibliographic records are published in catalogs or library indexes. A form will include a written description of a book, journal article, essay, or any other published material, and will typically contain three main components: author, title, and publication information. Use this checklist as a guide when evaluating the source of information.

If one or two of the main components are missing, this does not necessarily deprive the source of its status as credible but should induce the researcher to treat it with increased caution. What can be solved by reviewing literature and information sources:

• Finalize your research questions;
• Understand why the research problem is essential;
• Find out what others have already done on this topic.

Based on the studied sources of information, you can create your hypothesis, which anyone has not yet discussed. When constructing, you must adhere to the following hypothesis dissertation structure:

• the hypothesis must be formulated clearly and accurately; otherwise, it can lead to confusion in the proof, since until the concepts that make up the content of the assumption are clarified, it is meaningless to even begin with confirmation;
• the hypothesis must remain unchanged throughout the entire proof or refutation, otherwise in the process of confirming the assumption, the so-called substitution of the thesis will occur;
• the hypothesis must be based on facts or judgments; otherwise, if at least one of the grounds is false, then its combination with other grounds will give an incorrect, complex judgment, from which both true and wrong conclusions can follow;
• the grounds (arguments) must be facts or judgments, the truth of which is established regardless of the conclusion; otherwise, a vicious circle will arise in the proof.

Hypothesis testing is usually done through practice. The practice's needs generate an assumption, and basically, decide whether an assumption is true or false. When testing a hypothesis, logical means also use. Testing an assumption and transforming it into reliable knowledge is a complex and lengthy process. Therefore, it cannot reduce to any one logical action. When testing an assumption, various forms and methods of confirming or refuting it are used.

For example, direct confirmation (refutation) of the assumption. The essence of this method lies in the fact that the alleged individual facts or phenomena in the course of subsequent cognition are confirmed (or not confirmed) by the practice of observing legal phenomena.

Logical confirmation (refutation) proceeds indirectly since phenomena that have taken place in the past or exist at present but are inaccessible to direct sensory perception cognize.

To make it easier to view the hypothesis, you can use the phrase - "if ... then." You will see two variables in the sentence - independent, which is in the first part, or dependent, in the second part of the sentence. For instance:

• If a student spends more time studying and attending lectures, then his scores will become much higher.

Also, in academic hypotheses, you can use the technique of an unexpected effect. In the study, you immediately indicate the relationship between the variables, thus not allowing the dragons to doubt your assumption. For instance:

• Because the student will devote a lot of time attending lectures, he will manage to solve tasks better and get high scores.

If you use two methods, then using a hypothesis, you can indicate in the document what difference you saw. For instance:

• Statistics show that students who do not miss lectures receive higher scores than those who can attend only a few lectures.

To complete the hypothesis writing process, you must create a null hypothesis. This statement glast that there is no relationship between the measured phenomenon and the independent variable. You don't have to make sure that the null hypothesis is correct and do your research. Quite the opposite, you need to prove that there is a relationship between the variables, and your assumption is true.

One way for the student to prove this is not the case, and that is to reject the null hypothesis. If you abandon the assumption, it does not mean that the research was bad or did not give positive results. On the contrary, departing from one idea, you will have new thoughts on making further research even more interesting. For you to distinguish new hypotheses from the null hypothesis, you need to designate it as H0.

The null hypothesis is needed by the student to be sure that the results obtained are true, its confidence level should range from 95 to 99 percent. We leave exactly one percent in case someone nevertheless proves that your assumption is not correct. For example, another student will see mistakes and recheck them, come to a completely different result, then your work on this factor will be wrong. This is one of the reasons why it is essential to repeat experiments.

If you are just getting acquainted with this type of work, we want to provide several ways to find a hypothesis. One of the primary sources is dissertation examples of other students. You have the opportunity to come across the assumption that you need, but you did not know how to formulate it. Based on the information received, create a similar one, but do not entirely copy.

If you haven't found a suitable option, then personal experience comes in handy here. For example, you volunteered for a rally about drug abuse and teen crime because of them. You've probably heard a lot of slogans, and maybe there was one that caught your attention. Feel free to use it. Dig into your memory and remember the moments; perhaps you observed similar situations, this will also come in for inspiration.

And the most proven way to find an assumption is to contact StudyBay professionals. Because dissertation writing takes place online, you do not need to spend money on travel; you need to leave a request for feedback, and the manager will call you back or write to you. Professional authors have many reviews, which confirms their reliability. They will explore many resources and help you create the best hypothesis that will surprise all readers.

Decide whether to include research questions and hypotheses, or just one or the other

As a general rule in quantitative dissertations, it is more likely that a marker would expect you to have set out hypotheses (whether research or null hypotheses) rather than quantitative research questions. However, quantitative research questions and research hypotheses are designed to accomplish different tasks, which is one reason why it can be useful to include both:

RESEARCH QUESTIONS explain the purpose of the research. In other words, what issue or problem is the research trying answer? In terms of quantitative research questions, the type of research question (i.e., descriptive , comparative or relationship ) helps to explain the purpose of the research:

Descriptive research question What are the most important factors that influence the career choices of Australian university students?

Comparative research question What is the difference in student performance between teaching method A and teaching method B?

Relationship-based research question What is the relationship between gender and attitudes towards music piracy amongst adolescents?

RESEARCH HYPOTHESES explain the predictions being made (or otherwise) by the researcher based on specific hypothesis statements . These hypothesis statements set out what problem or issue the research is trying to answer, as well as their directionality , which help to explain any predictions being made by the researcher. Whilst descriptive research questions are better addressed in the form of research questions, comparative and relationship-based research questions can be restated as research hypotheses, as we illustrate below:

Comparative hypothesis Teaching method A will increase student performance more than teaching method B

Relationship-based hypothesis Adolescent females will have more negative attitudes towards music piracy than adolescent males

If your research hypotheses build on the research questions you have set, especially if there are multiple research hypotheses used to address a single research question, we would recommend using research questions and research hypotheses. However, if this is not the case, we would recommend using hypotheses rather than research questions ( NOTE: these are general rules and there is no 'law' to say that you cannot set research questions instead of hypotheses. Nonetheless, it's best to check with your supervisor if you choose not to use hypotheses).
