Sample text

We want to say that frustration leads to aggression all the time, not merely in the afternoon. On the other hand, if such a restriction were indeed true, it would be important that we know about it. Otherwise we would continue to deceive ourselves and claim unwarranted generality for our hypothesis as long as we continued to test subjects only in the afternoon. Also, what at first glance appears to be a trivial variable may turn out to have fascinating conceptual properties. The researcher may be able to deduce important psychological reasons why subjects behave so differently in the afternoon than in the morning.

We might obtain a null hypothesis outcome because of a defective dependent variable measure. We may have chosen a poor measure of aggression, or perhaps a very insensitive measure. If the measure is so insensitive that a subject must be practically paralyzed with frustration before he shows more aggressive responses than a nonfrustrated subject, then a null hypothesis outcome is virtually certain. Constructing good dependent variable measures is a creative bootstrap operation. In that respect, measuring the dependent variable is similar to constructing the independent variable.

7 and Fig. ) In a 2 X 2 factorial experiment there is not one but three sources of variation that may be tested for significance. These sources are: (a) effect of first independent variable, (b) effect of second independent variable, and (c) the interaction between the first and second independent variables. The effects of (a) and (b) are usually referred to as main effects, while (c) is simply called the interaction effect. A schematic summary table for a 2 X 2 factorial follows for the two independent variables noted above.
