Question

CureAll, a pharmaceutical company, develops a new drug to treat restless legs syndrome. An experiment to test the drug's efficacy is designed in such a way that neither the experimenter administering the drug nor the participants are aware of which participants are in the experimental group and which are in the control group until the results are calculated. CureAll is using ________ to test the drug's efficacy.

Answer 1

Answer:

double-blind experiment

Explanation:

A double-blind experiment is one in which both the experimenter and the subjects don't have knowledge of which treatment is given to which participant.

The aim of this method is to avoid bias especially from demand characteristics (experimenter expectation) and placebo effect (perception of benefit from an ineffective substance).

Double-blind experiment is used when CureAll develops a new drug to treat restless legs syndrome, and test the drug's efficacy is designed in such a way that neither the experimenter administering the drug or participants knows which drug is administered.
