What characterizes an experimental group in research?

An experimental group is characterized by its role in research where it receives the treatment or intervention being tested. This group is essential for establishing the effects of the treatment in question, allowing researchers to observe changes in response to the experimental conditions. The results from the experimental group are then compared to those of a control group, which does not receive the treatment, to determine whether the observed outcomes can be attributed to the intervention or if they occur due to other factors.

The distinction and role of the experimental group are central to experimental research design, making it possible to infer causal relationships and understand the impact of specific variables. In this context, the experimental group helps validate hypotheses and contributes to the overall understanding of the research question being addressed.
