How to Write a Hypothesis

how to write a hypothesis for research

What is a Research Hypothesis?

A statement that can be tested with the help of experimental or theoretical research is known as a hypothesis.

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

Data analysis and results will help you to 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 is to predict an answer to the research question based on existing theoretical knowledge or policies.

Some studies may have multiple hypothesis statements depending upon the research question(s).  it is necessary that a research hypothesis should 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 Hypotheses

Developing a hypothesis is easy, most research studies have two or more variables in the hypothesis, in particular studies correlational and experimental research. The researcher can control or change the independent variable(s) while measure and observe the independent variable(s).

“How long a student sleeps affects test scores”.

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 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.

Developing a Hypothesis

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

Ask a question

A research question is a starting step for writing a research hypothesis in the dissertation. The question should be re-searchable within theories/constraints, specific, focused, and answerable within the given time frame.

This is a critical part of writing a hypothesis because you will be able to write a perfect hypothesis when you have adequate knowledge about the topic.

Search for relevant theories and studies which can help you improve your knowledge on the subject topic. You can also create some conceptual formats to identify the variables and their relationship for your study.

Formulate Your Hypothesis

Do you have a testable and specific hypothesis? If not, there are plenty of ways to phrase the thesis. Your hypothesis should contain:

  • Variables according to the research problem you wish to address
  • The relevant area of study
  • Expected outcomes

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. Realising the meaning of research hypothesis will be easier by understanding the below research hypothesis example;

“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 researches provide correlation of 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.

Write a Null Hypothesis

If the statistical analysis is involved in your research, then you must create a null hypothesis. If you are finding 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 “How to test the research hypothesis in the dissertation”.

H0: The number of Zumba fitness classes attended by the obese lady has no effect on health.

H1: The number of Zumba fitness classes attended by the obese lady has a positive effect on health.
