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.
It's important to control your experiment so that you can be sure the results are due to the experimental variable (independent variable) and not something else.
If you do not have a control,then you cannot compare your test results.
The control is whatever you base your experiment on. No control = you can't compare your data to anything = good luck making sense out of your experiment. You aren't following the scientific method if there is no control.
so that it doesn't go out of control
In an experiment, a positive control is used to show that the experiment can detect a specific response, while a negative control is used to show that the experiment does not detect a response when it should not.

a control group assures that an experiment will be repeatable
A "Negative Experiment" is one where the expected result of the experiment is not found. These experiments are critically important and represent important work in Physics. The Michelson-Morley experiment, a "negative experiment" is one of the most important in the history of science. It was an test to measure the influence of the presumed etheric medium on a beam of light. No effect was found. Thus no ether.
The negative control in the lactose experiment would be a sample that does not contain lactose or the enzyme needed to break down lactose. This control is used to show what would happen if no lactose were present for the enzyme to act on.

in an experiment cantrolling variable is important as it helps to identify the limiting factors are present in the experiment, and also factor that do not necessarily affect the experiment.

A negative control is a control group in an experiment where the variables are not expected to have an effect. It helps researchers to determine if any observed effects are due to the treatment being tested or other factors.
