Quizplus · Accepted Answer

Control groups, random assignment, and statistical adjustment are all effective ways to control for regression toward the mean and placebo effects. Control groups ensure that any observed changes are not simply due to chance or the effects of time, while random assignment helps to ensure that any observed changes are due to the treatment being tested rather than pre-existing differences between participants. Statistical adjustment can also be used to control for confounding variables that may affect the outcome of the study. Double-blind testing and placebo controls can also be useful in controlling for placebo effects, but they are not mentioned as options in the given answers.
