Question

A professor decides to perform an experiment with two of his classes. He believes that students in a hot classroom do not learn well. In one class, he leaves the room temperature at 70 degrees (normal room temperature). In another class, he turns the temperature up to 85 degrees. At the end of the semester he gives the same final exam to students from each classroom to see if one group has learned significantly more than the other. (Overall, a highly unethical study.)
In this experiment, who would be the experimental group?
A) The 70-degree class.
B) Because of ethics, there was no experimental group.
C) The 85-degree class.
D) Both groups are experimental groups.

Answer 1

Answer: C) The 85-degree class.

Explanation: An experimental group simply refers to the participants who are subjected to the actual treatment during a study. In the scenario above, the groups of participants are involved, while the first group were subjected to seventy degree temperature, which corresponds to the normal oom temperature, this means they weren't subjected to any actual treatment. The other group however witnessed a temperature higher than the normal at 85 degrees and as such makes them the experimental group.
