Question

Quizplus · Accepted Answer

In a two-way factorial design, there are two factors being studied, each with two levels, resulting in a 2x2 design. This allows for two main effects (one for each factor) and one interaction effect (which measures the combined effect of both factors on the outcome). Therefore, the best choice is C, with two main effects and one interaction effect. The other options either overestimate the number of interaction effects or underestimate the number of main effects.
