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: -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-3: -What is a Double-Blind Study? When experiment studies are conducted, they usually involve the use of a treatment group and a control group. The treatment group is the part of the sample that receives the treatment being tested while the control group receives a placebo or no treatment at all.
