Mattie Hodge · Answer 1

Avoid observer and subject bias

Explanation:

Double-blind study is a human clinical trial method where neither the examiner nor the examiner knows what is being used as a variable at any given time. The purpose of the double-blind test is to avoid any conscious or unintentional interference with the results of an experiment and thus to avoid observer or subject bias in the result of the experiment.
