Answer:
experimental
Explanation:
The study of a new compound goes through an experimental methodology where patients are divided into two distinct groups. One group receives placebo and the other group receives the test compound. This group is the experimental group. Neither group knows exactly what they took. Thus, scientists can identify the results of medication in the body of experimental patients and can isolate the psychological effects observed in the group receiving placebo.
Note: Placebo is the same as flour pill, has no effect.
