Question

Quizplus · Accepted Answer

A reversal design involves the introduction and removal of the independent variable (also known as the treatment or intervention) one or more times to observe its effect on the dependent variable. This design allows for comparison of the dependent variable's behavior with and without the treatment and is a type of small-n design. Non-equivalent control group and pretetest/posttest designs are different types of experimental designs that involve comparing two groups, whereas a reversal design typically involves a single participant.
