Quizplus · Accepted Answer

Random assignment helps eliminate bias by ensuring that each participant has an equal chance of being assigned to any of the groups being studied. It also spreads out preexisting differences between participants among the groups, helping to control for potential confounding variables. By doing so, it helps maintain the integrity of the research by ensuring that any differences observed between the groups can be attributed to the treatment or intervention being studied, rather than to preexisting differences between the participants.
