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.
A group that receives no treatment is called the control group. The control group is there to compare the results between a group that has been exposed to diffent conditions, and one that has not.
The group that is not altered in an experiment is the control group, because all conditions are kept the same.
In a scientific experiment it is common to split your sample into (at least) two groups. Say you were to study the effect of a new drug on a specific condition, you would have a sample (a group of people with the condition in question e.g. breast cancer), and you would treat all members of the sample the same, with the exception that one group is give the actual drug, and the other group is given a "fake" pill. This fake pill is also called a placebo. The group that is given the real drug is called the experimental group, and the group that is give the placebo is called the control group. This setup attempts to ensure that any effect that is observed is caused by the drug (the experimental condition).

Anyone. AB can receive from anyone and positive can receive from positive and negative.
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.

The members of an experiment that receive "special treatment" are known as the "Experimental Group".The member of an experiment that don't receive "special treatment" are known as the "Comparison Group".Sources: Invitation to Life Span by Kathleen Stassen Berger
The group which does not receive experimental treatment is the control group, the group which does receive the treatment is the experimental group.
Experimental group
In such cases the group is called the control group.
A group that receives no treatment is called the control group. The control group is there to compare the results between a group that has been exposed to diffent conditions, and one that has not.

The control group.
In a controlled experiment, there are two groups. The control group is a group that nothing happens to. The experimental group is the group that you subject to the variable with which you are experimenting. At the end of the experiment, you test the differences between the control group, for whom nothing happened, and the experimental group, which received the variable. The difference (or similarities) between the two groups is how your results are measured.A control group is the group used for comparison in an experiment. One group receives the treatment that is being tested by the experiment; another group (the control group) has the exact same controlled environment, but does not receive this treatment. The effectiveness of the treatment can then be established by comparison with the control 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!!! :)
the control group does not receive receive an experimental treatment but stay in the same environment.
