Complex designs enhance researchers' ability to test hypotheses derived from theories because complex designs
A) require more specific operational definitions of concepts.
B) make it possible to test both main effects and interaction effects.
C) have higher internal validity.
D) insure that the null hypotheses will be false.

Question

Quizplus · Accepted Answer

Complex designs allow for the testing of both main effects (the effect of each independent variable on the dependent variable) and interaction effects (how the effect of one independent variable on the dependent variable changes across the levels of another independent variable). This capability enhances researchers' ability to test nuanced hypotheses that stem from theories, providing a more detailed understanding of the phenomena under study.
