In experimental research, what do we call the subjects that are compared to the treatment group?

Experimental Group
Control Group
Sample Group
Treatment Group

The correct answer is: Control Group

In experimental research, the subjects that are compared to the treatment group are referred to as the control group. This group serves as a baseline to evaluate the effects of the treatment or intervention applied to the experimental group. The control group does not receive the treatment or receives a standard treatment, allowing researchers to control for external variables and establish a clearer cause-and-effect relationship. By comparing outcomes between the control group and the treatment group, researchers can assess the efficacy of the treatment being studied. The control group is essential to ensure that any observed effects in the treatment group can be attributed to the treatment itself rather than other factors. This design strengthens the validity of the research findings.
