Control Group: A control group is the group in an experiment that does not receive the treatment or manipulation being studied. It serves as a baseline against which the experimental group can be compared.
Independent Variable: The independent variable is the variable that is manipulated or changed by the researcher in an experiment. It is what researchers believe will have an effect on the dependent variable.
Dependent Variable: The dependent variable is the variable that is measured or observed in an experiment. It is expected to change as a result of manipulating the independent variable.
