Question

Quizplus · Accepted Answer

Random assignment is a method used in experiments to distribute participants across various groups in a way that each participant has an equal chance of being assigned to any group. This process helps ensure that the groups are comparable at the start of the experiment, allowing researchers to assume that the groups are more or less equivalent on preexisting conditions. This equivalence is crucial for isolating the effects of the independent variable being studied, as it minimizes the impact of confounding variables.
