Quizplus · Accepted Answer

A factorial research design allows a researcher to examine all of the possible combinations of two or more independent variables. Main effect refers to the overall impact of a single independent variable on the dependent variable. Interaction effect refers to how the effect of one independent variable on the dependent variable depends on the level of another independent variable. Single-factor design only involves one independent variable.
