Detailed explanation-1: -The control group is the group in an experiment that does not receive any change in the variable. This group is left as natural as possible and used as a control to see if there is a change from the normal results. Only one variable should be changed at the time between the control group and the experimental group.
Detailed explanation-2: -The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group. The independent variable is “controlled” or held constant in the control group.
Detailed explanation-3: -The independent variable is the one that is changed by the scientist. To insure a fair test, a good experiment has only ONE independent variable. As the scientist changes the independent variable, he or she records the data that they collect.
