In an experiment, what is the group that receives the treatment called?

The group that receives the treatment in an experiment is referred to as the experimental group. This designation is essential because this group is subjected to the independent variable that the researcher is studying, which allows for the observation of any effects that the treatment may have.

It’s important to differentiate this group from others in the study, such as the control group, which does not receive the treatment and is used for comparison purposes. By measuring differences in outcomes between the experimental group and the control group, researchers can more accurately determine the effectiveness of the treatment being tested. The experimental group is crucial for demonstrating the cause-and-effect relationship that is often sought in experimental research.
