Question

Quizplus · Accepted Answer

Interactions in the context of ANOVA (Analysis of Variance) tests indicate that the effect of one independent variable on the dependent variable changes depending on the level of another independent variable. This means that the combined effects of the independent variables on the dependent variable are not simply additive, and the pattern of differences cannot be predicted by looking at the main effects of each variable alone. Choices B, C, and D describe situations that are not characteristic of interactions.
