Detailed explanation-1: -To minimize bias, it is good practice to work “blind, ” meaning that experimenters are unaware of the identity or treatment group of their subjects while conducting research.
Detailed explanation-2: -Random Assignment. The primary way that researchers accomplish this kind of control of extraneous variables across conditions is called random assignment, which means using a random process to decide which participants are tested in which conditions.
Detailed explanation-3: -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.
