What Is a Control Group?
Control group refers to a randomly selected subset of experimental subjects, in which individuals have no special treatment. The reason for the need for a control group is that without a control group, there is no way to determine whether such an operation or some other variable (or several joint variables) has had an effect.

- In biological comparison experiments (or control experiments), there is only one variable. In this variable, those who are close to real life are called the control group, while those who are away from real life are called the experimental group.
- In statistics, the control group refers to a randomly selected subset of experimental subjects. In this subset, each unit does not receive some special treatment received by members of the experimental group.
