Detailed explanation-1: -A type of clinical trial in which neither the participants nor the researcher knows which treatment or intervention participants are receiving until the clinical trial is over. This makes results of the study less likely to be biased.
Detailed explanation-2: -The correct answer is a blind experiment.
Detailed explanation-3: -A double-blind study withholds each subject’s group assignment from both the participant and the researcher performing the experiment. If participants know which group they are assigned to, there is a risk that they might change their behavior in a way that would influence the results.
Detailed explanation-4: -Therefore, both research participants and researchers are blind to this information. Double-blind studies help in reducing the biases like the placebo effect, experimenter bias, and experimenter expectancy effect that hinder the results and conclusions of the study.
Detailed explanation-5: -Medication Experiments A double-blind experiment is beneficial when testing a specific medication. Half of the participants are given the medication, and the remaining participants are given a placebo. A placebo is an inactive substance such as a sugar pill that looks identical to the medication.
