AP PSYCHOLOGY

Detailed explanation-1: -A double-blind study is one in which neither the participants nor the experimenters know who is receiving a particular treatment. This procedure is utilized to prevent bias in research results. Double-blind studies are particularly useful for preventing bias due to demand characteristics or the placebo effect.

Detailed explanation-2: -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-3: -The double-blind design describes an experimental procedure in which neither the participant nor the experimenter are aware of which group (i.e., experimental or control) each participant belongs to.

Detailed explanation-4: -Double-blind experiments are scientific experiments with a control group and an experimental group in which the participants and researchers are both unaware of group assignments. These experiments are an essential part of empirical research, especially in the social sciences.

Detailed explanation-5: -The common term “double-blinded” refers to full avoidance of performance bias by blinding both participants and personnel [6]. Detection bias refers to the risk of how the evaluation of the outcome bias effects. Blinding of outcome assessors reduces detection bias.
