Quizplus · Accepted Answer

Random assignment is the best method for ensuring equivalence between experimental and control groups. This method involves randomly assigning participants to either the experimental or control group, which helps to ensure that any individual differences between participants are evenly distributed across both groups. This reduces the risk of confounding variables impacting the results of the study, which can help to increase the internal validity of the research.
