Basically, the one group pretest and posttest design is an experimental research design where there is only one group of sample of which is given a pre-test given before the intervention is given and a post test where the intervention has already been given. After this, the results of the pre test and post test are compared for the analysis.
The control group in an experiment is the group that nothing is done to. The reason why there is a control group in experiments is to compare it with the group that has been tested.

A control refers to the "control group" in a scientific experiment. The control group is compared to the experimental group. For example, pretend you are experimenting to see if a drug works. Group A (The experimental group) is given the real drug, and Group B (The control group) is given a fake drug (placebo) to compare results.
the control group is the group or subject that is not affected by what you are testing for.
