Decide first whether data are quantitative or qualitative. Unless mentioned otherwise, no assumption has been seriously violated, and therefore the appropriate test should be selected from among t, F, or c2 tests. Specify the precise form of the test. For example, specify that the t test is for two population means with related samples, or that the c2 test is for two variables, or that the F test is for repeated measures. A comparative psychologist suspects that chemicals in the urine of male rats trigger an increase in the activity of other rats. To check this hunch, she randomly assigns rats, in equal numbers, to either a sterile cage, a cage sprayed with a trace of the chemicals, or a cage sprayed thoroughly with the chemicals. Furthermore, to check out the possibility that reactions might be sex-linked, equal numbers of female and male rats are assigned to the three cage conditions. An activity score is recorded for each rat during a 5-minute observation period in the specified cage.
