Does experimental group have control group and cause and effect?

An experimental group does not inherently have a control group; rather, it is the framework of the entire experiment that typically includes both. The experimental group receives the treatment or intervention being tested, while the control group does not, allowing for comparison. This setup is crucial for establishing cause and effect, as it helps isolate the effects of the treatment by controlling for other variables. Thus, the presence of a control group strengthens the validity of causal conclusions drawn from the experiment.
