Which of the following is an advantage of using factorial designs versus single-factor designs?

A) Factorial designs allow researchers to determine whether interaction effects are present among independent variables.
B) The interpretation of factorial designs is simplified by the presence or absence of interaction effects.
C) Testing and interpreting effects in a factorial research design is less complicated than single-factor designs.
D) Factorial designs allow for test the significance of each dependent variable separately from the others.

Question

Markelle Fletcher · Accepted Answer

Final Answer : A, Explanation :  Factorial designs allow researchers to examine the effects of multiple independent variables and interactions between them. This allows for a more comprehensive analysis of the factors that influence the dependent variable, and can reveal complex relationships between variables that would be missed with a single-factor design. A is the correct answer because it highlights the advantage of factorial designs in detecting interaction effects.
