The control group in an experimental study will
a.) be excluded from the results of the experiment if they contradict the hypothesis b.) receive no treatment during the experiment
c.) be informed at the outset of the experiment that they are the control group d.)receive the same treatment as the experimental group

The correct answer is the following: option B. The control group in an experimental study will receive no treatment during the experiment. Within an experimental study, the control group is the one that does not receive any sort of treatment. This is done to keep track of what the subject is normally, without taking any treatment, so that they can compare it to the experimental group, which is the one that takes the treatment. The control group is the standard to which comparisons are made in an experiment.

that's conceptually impossible.
