Quizplus · Accepted Answer

A reversal design involves introducing and removing the independent variable one or more times to observe its effects on the dependent variable. It is a type of small-n design, which focuses on the behavior of individual participants rather than group averages. Nonequivalent control group and pretest/posttest designs involve different types of experimental control and do not typically involve introducing and removing the independent variable.
