Question

Quizplus · Accepted Answer

In a double-blind experiment, both the subjects and the researchers are unaware of which group is the experimental group and which is the control group. This reduces the potential for biased results since neither the subjects nor the researchers can unintentionally influence the outcome of the study. Both groups are treated the same, and any differences observed can be attributed to the treatment being tested.
