The control group gives you something to compare the results to. For example, in a medical trial for a new medicine, one group will receive sugar pills. Without this control group, it means nothing if 50% of those treated with the real medicine get better. The control group may have the same results, better results, or worse results. This tells how effective the medicine is. The same is done with any type of experiment.

Yes 99.99% of the time,controls are very necessasry.If you are performing an experiment testing some variable, say (X) , you need to perform a control where everything is the same as the experiment conditions including your (X) variable your testing in the experiment. Therefore, the only difference between your control and your experiment is the variable your testing.Since the variable in your control is kept constant, you can compare the result so the experiment (where the variable was varied) and your control (where the variable was kept constant).Since all other factors in both the control and experiment were the same, you can compare your results
a control is something that stays the same in an experiment
control means to take conrol in a science experiment
The control of an experiment is the part of an experiment that does not change, and is strictly used as a comparison to the variable that is being tested.
A control is needed in a valid experiment because without controls then more then one variable is being tested. This can mess up the results.

He needed a control group. *Apex*
The treatments can be compared to each other instead of to a control
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.
