In the controlled experiments, there are dependent and independent variables. The independent variable will get modify generally and is compared to the control. The variable, which is determined in an experiment is considered as the dependent variable. It relies upon the independent variable of the experiment. The control group in an experiment is created similar in each circumstance in an experiment. The control group is the one, which is compared with the experimental group.
