Suppose you are conducting a factorial study with variables A and B. Your results reveal an interaction effect. This means that
A) variable A is effective in changing performance only if variable B is also effective.
B) the effect of independent variable A depends on what level of independent variable B they experience.
C) one of the variables, A or B, can have an effect on performance only if the other does not.
D) the effects of variable A and of variable B cancel each other out.

Question

An interaction effect in a factorial study indicates that the effect of one independent variable on the dependent variable changes depending on the level of the other independent variable. This means the influence of variable A on the outcome is different at different levels of variable B, and vice versa.
