You must have a control group, an experimental group, an experimental variable (also called the independent variable), and a response to be measured (also called the dependent variable). The experimental variable is applied only to the experimental group, so that any difference between the control group and experimental group is due only to the experimental variable. Both the control group and experimental group must have the same conditions, except for the experimental variable.
control group
A group in an experiment that acts as a standard of comparison is called a control group. This group does not receive the experimental treatment or intervention and is used to compare results against the experimental group, which does receive the treatment. By maintaining the control group's conditions constant, researchers can better assess the effects of the independent variable on the dependent variable.
Experiments typically involve:1) Experimental group: the group of subjects exposed to the variable being tested.2) Control group: should be as identical as possible to the experimental group, but is deliberately not exposed to the experimental variable - this provides a baseline measure from which the effect of the variable can be determined.
The control group does not change, while the experimental group is the variable you are changing.
The effect on the dependent variable will be different in the experimental group than the control group, which is why you measure the dependant variable.

control group
That group is called the experimental group, and it is used to test the effect of changing the specific factor that distinguishes it from the control group. By comparing the results of the experimental group with the control group, scientists can determine the impact of that particular factor on the outcome of the experiment.
A control group is the standard of comparison between what happens with the experimental variable and without the experimental variable.
The experimental group is the group in an experiment that receives the manipulation of the independent variable. This group is compared to the control group, which does not receive the manipulation, to determine the effect of the independent variable on the dependent variable.
The control group does not change, while the experimental group is the variable you are changing.
The factor is called the independent variable. This is the variable that is deliberately changed by the experimenter in the experimental group to see its effect on the dependent variable.
The factor that differs between the control group and the experimental group in an experiment is the independent variable. This is the variable that is intentionally manipulated or changed by the researcher to observe its effect on the dependent variable.
