What is the difference between a control group and a treatment group?

Control and Treatment Groups: A control group is used as a baseline measure. The control group is identical to all other items or subjects that you are examining with the exception that it does not receive the treatment or the experimental manipulation that the treatment group receives.

What is the importance of control groups?

Importance of control groups Control groups help ensure the internal validity of your research. You might see a difference over time in your dependent variable in your treatment group. However, without a control group, it is difficult to know whether the change has arisen from the treatment.

What is an untreated control group in research?
