Answer:
double blind study
Explanation:
The technique of separating the study group into two and one receiving placebo and the other receiving the substance serves to eliminate the psychological effects of patients and to capture the actual effect of a substance studied on each person's organism. However, there are studies in which not even the researcher knows which group received each substance, this type of study is called double blind study. This tactic serves to eliminate the selection bias that can happen in the researcher. If he knows which group received placebo and which group received the substance, he or she may, albeit unintentionally, make a subjective judgment of the experiment. However, by using the double-blind study, the researcher will not have any influence on the results, he or she will only observe the results without any psychological interference.
