Document Summary
When a graph is useful, graph the data: specify where pairwise comparisons are required. Note that you do not have to conduct such comparisons. When a solution to a problem is required, specify statistical null and research hypotheses, and identify the rejection region for the null hypothesis. Describe in words, the results of your statistical analyses: a pharmacologist was interested in how an anti-depressant drug affected a patient"s mood. To manipulate mood she chose two movies, the killing fields, and woody allen"s hannah and her sisters. To evaluate the effects of the drug she randomly assigned 8 of 16 manic-depressive patients who had volunteered for this experiment to receive the drug while the other eight were given a placebo. After being on the drug for 1 month, 1/2 of the patients receiving the drug were randomly assigned to view the killing fields while the other half viewed hannah and her sisters.
