What is the purpose of an experimental group in research?

The purpose of an experimental group in research is to receive the treatment or manipulation that is being tested. This group is essential for determining the effects of the independent variable on the dependent variable. By exposing this group to the specific conditions that the researcher is studying, it allows for the examination of any changes or outcomes that result from the treatment.

For example, if a researcher is testing the effectiveness of a new drug, the experimental group would receive the drug, while the effects observed in this group can be compared against the control group, which does not receive the treatment. This comparison helps in establishing any causal relationships and understanding how the treatment impacts the subjects.

In terms of research design, the experimental group plays a critical role in validating the hypothesis being tested and providing insights into the effectiveness of the intervention.
