Question

Quizplus · Accepted Answer

The double blind technique is used to control for experimenter bias, which occurs when the experimenter's expectations or beliefs influence the results of the study. By keeping both the experimenter and the participants unaware of who is receiving the experimental treatment, this bias can be minimized. Selection bias is controlled through randomization, a poorly defined dependent variable is not controlled by the double blind technique, and individual differences among subjects are controlled through statistical analyses or other experimental design techniques.
