If you disprove a null hypothesis, that is evidence for a relationship between the variables you are examining. A null hypothesis, denoted by H0, proposes that two factors or groups are unrelated and that there is no difference between certain characteristics of a population or process. Data would also be obtained from a group of students whose behaviors and environments were not controlled. For a hypothesis to be sound, hold tight to these tips. The alternative hypothesis would probably state "five additional hours of study time per week does not increase the grade point average of college students."
