Question

Quizplus · Accepted Answer

Random assignment involves assigning participants to treatment conditions at random, which helps ensure that participants' characteristics are equally distributed across the groups. This reduces the likelihood of confounding variables, which may affect the results of the study. Sequential or systematic assignment does not involve randomization, which may result in biased results. Correlational assignment does not make sense as it is not a method of assignment.
