7 Σεπ 2024 · A control group in a scientific experiment is a group separated from the rest of the experiment, where the independent variable being tested cannot influence the results. This isolates the independent variable's effects on the experiment and can help rule out alternative explanations of the experimental results.
Example of a Control Group. Suppose we want to determine whether regular vitamin consumption affects the risk of dying. Our experiment has the following two experimental groups: Control group: Does not consume vitamin supplements. Treatment group: Regularly consumes vitamin supplements.
