Imagine a research wants to study the effect of being happy on helping others. To study this, he brings participants into the lab and randomly assigns them to either to receive a compliment (and thus induce a positive mood) or to receive no compliment (a neutral mood). In addition, he is interested in the effect of participant gender. The dependent measure is a 12-point helping scale which measures how likely participants are to engage in future helping behavior (i.e., volunteering, donating money, etc.). Higher scores represent a higher likelihood to help. Below are 4 possible patterns of results. For each, describe the pattern of results (1 main effect, 2 main effects, interaction, or interaction plus main effects). Then, write a brief description of the conceptual meaning of each result.
