What is the group exposed to the independent variable in an experiment called?

The group exposed to the independent variable in an experiment is known as the experimental group. This is the group that receives the treatment or is subjected to the condition being tested, allowing researchers to observe how the independent variable affects the dependent variable. The comparison of results from the experimental group with results from a control group, which does not receive the treatment, helps to determine the effect of the independent variable. Understanding the role of the experimental group is crucial for interpreting the results of an experiment and establishing cause-and-effect relationships.
