Answer to Question 2

A theory is a formal, logical explanation of some events that includes descriptions of how things relate to one another. Ultimately, theory plays a role in determining the appropriate research objectives. A theory is built through a process of reviewing previous findings of similar studies, simple logical deduction, and knowledge of applicable theoretical areas. This logical explanation helps the researcher know what variables need to be included in the study and how they may relate to one another. A hypothesis is a formal statement explaining some outcome. Hypotheses must be testable and should be written as propositions. We often apply statistics to data to empirically test hypotheses. When the data are consistent with a hypothesis, we say the hypothesis is supported. When the data are inconsistent with the hypothesis, we say the hypothesis is not supported. Because our results are based on statistics, there is always the possibility that our conclusion is wrong, so from an absolute perspective, statistics cannot prove a hypothesis is true.
