A drug company is testing the effects of a new drug designed to prevent hair loss. Of the 2,000 people in the trial, 1,700 people receive the drug and the other 30 people receive a sugar pill. What is the purpose of the group receiving the sugar pill? A. The group is being used as the control group B. The group is being used as the dependent variable C. The group is being used as the independent variable D. The group is being used as the manipulated variable

A

Explanation:

The correct answer would be that the group being given the sugar pill is being used as the control group.

In a typical experimental study, there are two groups of subjects:

1. The treatment or the experimental group

2. The control group

The treatment group receives the treatment variable while the control group does not receive or is given a placebo. Thus, the control group act as the reference group for comparison basis. Any difference in the observation between the two groups would be attributed to the treatment variable.

The correct option is, therefore, A.
