Question

Quizplus · Accepted Answer

A factorial design is specifically designed to test the effects of multiple independent variables and all possible combinations of these variables. This allows researchers to analyze the main effects of each independent variable as well as any interaction effects between them. Option B) single-factor is not correct because it involves only one independent variable. Option C) interaction and D) main effect are not exclusive designs, as they can be present in a factorial design. Therefore, the best choice is A) factorial.
