Most research reports also present either a statement of purpose, research questions, or hypotheses, and often, combinations of these three elements are included. When you set up a hypothesis test to determine the validity of a statistical claim, you need to define both a null hypothesis and an alternative hypothesis. The clinical question is under which component? Most scientific hypotheses are proposed in the if-then format because it's easy to design an experiment to see whether or not a cause and effect relationship exists between the independent variable and the dependent variable. Scientists generally base scientific hypotheses on previous observations that cannot satisfactorily be explained with the available scientific theories.
