The group which does not receive experimental treatment is the control group, the group which does receive the treatment is the experimental group.
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.
In an experimental design comparing two groups in which one group gets one treatment and another group gets a second treatment, the experimental group is the group with the "different" treatment. The control is the "usual" treatment; the experimental group gets the "new" treatment. Of course, things get complicated with more complicated "experiments."
There is one major difference of a treatment group and a control group. The treatment group is treated with an experimental medication (or known medication), and the control group is treated with a placebo in place of the medication to measure effects of the medication.

the experimental group
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!!! :)
This would be the control group. The group that gets treatment is the test group. A control group is made to make sure the changes in the test group are not just coincidence.
Participants in an experimental study receive the treatment. Typically, participants are randomly assigned to either the treatment group, which receives the experimental treatment, or the control group, which does not receive the treatment or receives a standard treatment for comparison.
Independent variable
Experimental group
the control group does not receive receive an experimental treatment but stay in the same environment.
