Answer:

control group is a set of experimental samples or subjects that are kept separate and aren't exposed to the independent variable. ... A controlled experiment is one in which every parameter is held constant except for the experimental (independent) variable. Usually, controlled experiments have control groups

Answer:

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.

The purpose of having a control is to rule out other factors which may influence the results of an experiment.
