Question

Quizplus · Accepted Answer

The techniques that help control for regression toward the mean and placebo effects are control groups, random assignment, and statistical adjustment. Control groups are used to compare the effects of the treatment with those of a placebo or no treatment. Random assignment helps ensure that participants are assigned to treatment and control groups by chance rather than preference. Statistical adjustment is used to account for individual differences and other factors that may affect the results.
