Which group in an experimental study receives the intervention?

The experimental group is the one that receives the intervention in an experimental study. This group's main purpose is to observe how the intervention affects certain outcomes, allowing researchers to determine its efficacy or impact compared to the control group or other groups in the study.

By focusing on the experimental group, researchers can gather data on the specific effects of the intervention, making it possible to analyze and assess any changes or differences relative to other groups that did not receive the same treatment. This distinction is crucial in experimental research, as it helps ensure that any observed effects can be attributed to the intervention itself rather than other external factors.
