<h3>
Define experimental group in scientific study?</h3>
A experimental group in scientific study is defined as the researcher compares at least two groups during an experiment, a control group and an experimental group.
Because they are both made up of people from the same population, they are identical in every way except for the independent variables.
The therapy is administered to the experimental group. The researcher willingly alters the independent variable's values to see how it impacts the people who are being studied. Several experimental groups are possible.
