How to Write a Hypothesis – Steps & Tips
Published byat August 14th, 2021 , Revised On September 20, 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.
Research Hypothesis Definition
Not sure what the meaning of the research hypothesis is?
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.
Developing a Hypothesis
Here are the steps involved in how to write a hypothesis for a dissertation.
1. Ask a Question
A research question is a starting step for writing a research hypothesis in a dissertation. The question should be re-searchable within the given constraints. It should also be specific, focused, and answerable within the given time frame.
You will be able to write a perfect hypothesis when you have adequate knowledge about the topic. Make sure to acquire as much knowledge as possible on the topic you are exploring.
You can also create some conceptual formats to identify the variables and the relationship between them.
2. Formulate your Hypothesis
Do you have a testable and specific hypothesis? If not, then make sure your hypothesis:
- Includes variables according to the research problem you wish to address
- Is it relevant to your area of study
- Incorporates the expected outcome
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;
In academic research, you can write the predicted variable relationship directly because most research studies correlate terms.
If your research compares two groups, then you can develop a hypothesis statement on their differences.
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.”
