In order to study the effects of loud noise on worker productivity, Dr. McDuffee had one group of research participants work in a noisy room and a second group work in a quiet room. Those who worked in the quiet room were exposed to the condition

A) experimental

B) survey

C) control

D) correlational

The correct answer is C. control condition

Explanation:

In an experiment, it is common one group receives a special treatment, which is known as "experimental condition", while the other group does not receive this treatment, this condition is known as the control condition. Moreover, the control condition is relevant in the research because it can serve as a comparison to the experimental condition or special treatment.

In the case presented, the experimental condition would be the noisy room because this is the variable the researcher is studying in reference to worker productivity. Also, those who are not in the noisy or those in the quiet room are exposed to the control condition because they do not receive the treatment but serve a control to measure the changes in productivity in a noisy room.
