Experimental Group
Experimental Group
The group in an experiment that receives the treatment or intervention being tested. It's the group where researchers observe any effects caused by the exposure to the variable.
Control Group
Control Group
Used as a baseline for comparison in an experiment. This group does not receive the experimental treatment, ensuring a neutral starting point.
Example of Experimental and Control Groups
Example of Experimental and Control Groups
In a drug study, the experimental group receives the new drug, while the control group may receive a placebo or no treatment. By comparing the outcomes of both groups, researchers can isolate the effect of the drug itself.

Study Notes
Experimental Groups
- Exposed to the variable being tested.
- Receives the treatment under investigation.
- Observe any changes due to exposure.
- Example: Drug study participants receiving the drug.
Control Groups
- Used as a comparison baseline.
- Does not receive the experimental treatment.
- May receive a placebo or no treatment.
- Isolates the effect of the independent variable by comparing outcomes with the experimental group.
- Example: Drug study participants receiving a placebo or no treatment.
Key Distinction
- Experimental group receives the treatment; the control group does not.
- This difference allows researchers to determine if the treatment is effective.
