Derik wanted to know whether people will perform better on a math test if they have caffeine beforehand. So he put everyone in a lab, had them drink their coffee, and then begin their test. He gave half of the unknowing participants decaf, and the other half regular coffee. He then analyzed the results, and found that those who drank decaf scored significantly lower than those who were given normal coffee. In Derik's experiment, the control group consists of

The group with regular coffee

Explanation:

The control group in the experiment is the other half of the group that were given regular coffee. The researcher aims to test the effect of caffeine and so gives regular coffee to one group and caffeine to the other. This means that he aims to use one group-regular coffee group as a benchmark in measuring the other group- caffeine. The group with the caffeine is called the experimentation group as they the group tested while the other group is the control group as they are not tested but are merely benchmarks for measurements
