Describe the nature of each effect (e.g., there is a main effect of candy such that the sweeter the candy, the more people like it).

For each scenario below, indicate whether there are main effects for each IV and whether there is an interaction. If there is an interaction, indicate the type of interaction (spreading or crossover). Describe the nature of each effect (e.g., there is a main effect of candy such that the sweeter the candy, the more people like it).

Hints: You may find it helpful to compute the marginal means (to figure out if there is a main effect) and quickly sketch a line graph for each scenario (to figure out if there is an interaction effect).

The scenarios have been uploaded in the file below along with the notes of this chapter in order to help out.
