Controlled experiments contain two parts, the control group and the variable group. The variable group is the group that receives treatment and attention. These two groups are used to compare to each other at the end of the experiment.

Controlled (or control) variables are things that are kept the same during an experiment. There are usually many- for example, when testing how light intensity affects photosynthesis, the controlled variable would be the type of plant used, or the color of the light.

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
its the control of your experiment so it has no effect.
