How to write a hypothesis in 5 steps.
So, how do you create your own research hypothesis? Below we take you through the steps needed to write a hypothesis for an upcoming research paper, and the steps you need to take to get there.
1. Start with your research question.
The easiest way to write your hypothesis is to start with the question you want answered. Make sure it’s specific and focused on what your research is. For example: Do people who eat an apple everyday visit the doctors less?
2. Conduct some initial research.
It’s likely you already have an understanding of the question and topic, but now’s the time to carry out some initial research. Try to find previous research, data or case studies to get an understanding of what’s already out there, and see if you can respond or build on those to bring something new to the field.
3. Identify your variables.
Every hypothesis should contain at least two variables. These variables and the relationship between them is what you will then measure as part of your research.
There are two main types of variable within a hypothesis:
- Independent variable – what you can change or control.
- Dependent variable – what you’re going to monitor and measure.
At this stage of the research process, you’ll need to work out what your variables are. A simple way to do this is to follow the “If this, then that” framework to help you identify them. For example: “If I stay awake all night, then I will be tired tomorrow.” “If” is the independent variable (staying awake all night), while “Then” is the dependent variable (being tired tomorrow).
4. Write your hypothesis statement.
Once you’ve established your variables, you can start to construct your hypothesis statement into one clear and concise sentence. For example: People who eat an apple a day have fewer doctor’s appointments.
5. Refine your hypothesis.
At this point, you should check that your hypothesis is specific and testable. You can do this by taking apart your statement. Check that it has distinct variables and a clear prediction for the outcome of the analysis or experiment. Then you’re good to go.
