What is the difference between independent and dependent variables in experimental research?

In experimental research, the independent variable is the variable that is manipulated or controlled by the researcher. It is the variable that is believed to have an effect on the dependent variable. On the other hand, the dependent variable is the variable that is measured or observed to determine the outcome or effect of the independent variable. It is the variable that is expected to change as a result of the manipulation of the independent variable.
