Quizplus · Accepted Answer

Random assignment is important for experimental studies because it helps to minimize the effects of extraneous variables and increase the likelihood that the treatment group and control group are similar before the manipulation. Without random assignment, it is more difficult to make causal inferences because there may be pre-existing differences between groups that could account for differences in outcomes.
