In an experiment, what do we call the group that is exposed to the treatment, or one version of the independent variable?

In an experiment, the group that is exposed to the treatment or a specific version of the independent variable is known as the experimental group. This group is crucial for determining the effect of the treatment being tested, as it allows researchers to observe changes and outcomes resulting from the independent variable.

For example, if a scientist is testing the effectiveness of a new drug, the group that receives that drug would be the experimental group. By comparing the results from this group to those from the control group, which does not receive the treatment, researchers can assess the drug's impact accurately.

This distinction helps in understanding cause-and-effect relationships within the context of scientific research.
