Which group in am controlled experiment is not exposed to the experimental variable
Experimental group and Control group
In a controlled experiment, the experimental group is the group that has one variable changed.
An experimental group is the group in an experiment that receives some type of treatment. The control group in an experiment receives no treatment. And, in conclusion, sometimes it might not work so be careful!!! :)
Typically, in a randomised controlled trial (RCT), which is often used in testing the efficacy and use of drugs that about to be released into the market, there are two groups: The intervention group - receiving the treatment. The control group - receiving a placebo (hence the subjects believe that they're receiving treatment when they are not) Usually, patients are randomly allocated into the respective groups - otherwise this is known as a 'quasi-experimental' study.

An investigation in which a group that receives some experimental treatment is compared to a group that does not receive the experimental treatment can be called a placebo-controlled study or a comparative experiment, both of which are types of clinical studies. The group receiving the experimental treatment is called the treatment group, and the group that is not receiving the experimental treatment is called the control group.
