Without a control group, what would you compare your results to? How would you know if the treatments had any effect? Without a control group, there is no basis for knowing if a particular result is due to the variable being tested or to some other factor.
The control group gives a set where the expected outcome is known. So when a variable is changed and if the outcome is the same as the control group, then we know to try a different variable.
The control group doesn't get the drug, or the test, go through the procedure, or what ever it is you are studying. They are the "Zero" or "Baseline" that you compare all your test results to. Without a control group, you can't know if you get any results, good or bad

so that it doesn't go out of control
A control group is the unaffected group in a science experiment.
Because without it, it wouldn't be organized.
the answer to that question is the control group has nothing to do with the independent variable because a control group is some thing in your experiment that has not changed through out your experiment. And a independent variable is some thing in your experiment that you change through your experiment(s)
When performing an experiment it is very important to have a control set. It is important to have a control set because it ensures that the experiment can be repeated as many times as necessary.
a control group assures that an experiment will be repeatable
The control experiment allows a standard of comparison for the experimental group
Every experiment requires a control group. This is so that the group that is manipulated can be compared to a group that has had nothing done to it., in order to measure changes.

The control group
A control group is the standard of comparison between what happens with the experimental variable and without the experimental variable.
the group that does not change in the experiment VIVI :)
A test group is the group in an experiment to which the change is being applied and the control group is the same type of group in an experiment to which nothing is done to compare the changes in the test group to.

And a independent variable is some thing in your experiment that you change through your experiment(s)
