First, a tentative assumption is made about the parameter or distribution. Research hypothesis can be present in research and it may not be but if it is present it can have following benefits. How to Formulate an Effective Research Hypothesis. After determining a specific area of study, writing a hypothesis and a null hypothesis is the second step in the experimental design process. This kind of statement is a brief description of an experimental method followed by a prediction and is the most common way that hypotheses are misrepresented in science education.
