Question

Quizplus · Accepted Answer

Masked or blind study designs are used to deal with observer bias, which occurs when the observer's preconceived notions or expectations affect their interpretation of data. By masking the observer from certain information, such as the treatment group that a participant belongs to, the study attempts to eliminate observer bias and ensure more objective data interpretation. Yea-saying biases, bystander effects, observer effects, and interrater reliability are all different types of biases or sources of error in research, but they are not specifically addressed by masked study designs.
