Question

Experimenter bias can best be controlled using ________.A)  a placeboB)  double-blind controlC)  randomizationD)  subjects who do not know the purpose of the study

Kaylee Malli · Accepted Answer

Final Answer : B, Explanation :  Double-blind control involves neither the experimenter nor the subjects knowing which group is the experimental group or the control group, thus minimizing experimenter bias. Placebos can help control for the placebo effect, but not experimenter bias specifically. Randomization ensures equal distribution of variables, but does not directly control for experimenter bias. Choosing subjects who do not know the purpose of the study may help reduce participant bias, but does not control for experimenter bias.
