Question

Quizplus · Accepted Answer

The double-blind design is the most effective method of guarding against both experimenter bias and participant expectations. It involves neither the participant nor the experimenter knowing which group is receiving the treatment and which is receiving the placebo, making it less likely for either to influence the results. Confounds refer to variables that may interfere with the results, random selection is used for choosing participants and does not control for bias, and the placebo effect is the phenomenon of a person's belief in a treatment producing a real physiological response.
