Which of the following statements about factorial designs is TRUE?
A) A hypothesis that one variable moderates the effect of another can be tested only with a factorial design.
B) A factorial design can include either manipulated independent variables or correlational dependent variables, but not both in the same study.
C) In a counterbalanced within-subjects design an interaction between order of participation in experimental conditions and the independent variable means that order effects are not a problem.
D) It is not possible to have a factorial design with more than three conditions per independent variable.

Question

Quizplus · Accepted Answer

A factorial design allows for the simultaneous manipulation of two or more independent variables and allows for the testing of interactions between these variables. By manipulating multiple variables, factorial designs can test hypotheses regarding whether one variable moderates the effect of another. Therefore, statement A is true. Statements B, C, and D are all false.
