Q: How do I write a better description in the hypothesis?

You have two questions, one bigger, the other somewhat smaller or a result of the initial question. Let’s take the bigger one first.

How do you explain what will happen better in your study

For this, you’ll need to pull back a bit. The steps to arrive at a hypothesis are roughly as follows:

Gap > Research problem > Research question > Problem statement > Hypothesis

As your concern is about what will be better or different about your study (compared with similar ones in the same area), you’ll need to first identify gaps in existing studies. This is typically done through a comprehensive literature search. Once you’ve identified a gap (or more), you’ll need to narrow down to one (though there could be multiple, if they are related) for pursuing in your study. Then, you’ll have to keep distilling through each step until your hypothesis is reflective of the uniqueness of your research problem. In short, identifying a relevant gap will help you determine how your study will be better or different; the steps after that are more to articulate what your research will be about.

How do you write a better description in the hypothesis

A hypothesis has to predict an outcome that you will test in your study. You haven’t mentioned your area of study. So, we’ll use an example that most people should be able to relate with. For instance, if you are studying weight management, a hypothesis could be ‘Thirty minutes of high-intensity interval training (HIIT) is more beneficial than an hour of cardiovascular training.’ Based on this, you would need to chart out the methods of your study, including variables, participant groups, and duration (of study), and then, test that out in your study. Then, you would need to record the observations, analyze the findings, and see if they correspond with your hypothesis. If not, you may choose to go back and come up with another hypothesis.
