The defintion of a control group in an experiment is a standard for comparison. So then the purpose of the whole control group during an expirenment is to have something to compare your data to.
To help you conclude that no uncontrolled factors significantly influenced your results. To help you determine that your experimental results are valid To help control for factors that aren't being tested but might affect results
remains the same throughout the experiment
the purpose is how is is getting bigger
Control Variable = kept in constant in a experiment Experimental Variable = changes in a experiment
The control group stays the same throughout the entire experiment.
Having a control in an experiment allows you to see what happens when no variables are changed. If you do not have a control, you do not have anything to compare your results with after changing variables of the experiment.
To have something to compare the rest of the experiment to
to control another animals
the control for multiple variables in a experiment
The purpose of a control variable in an experiment is to allow the experiment to come out with accurate results. It makes it a lot easier to measure the results when different things aren't affecting it.

people can do almost ANYTHING if they have your social security number
A control setup is something where you know how it will behave. It gives you a reference to measure affect of all other variables.
The purpose of a control group is to show what would happen under normal conditions. It serves as a comparison to the results you receive from the manipulation of the independent variable on the dependent variable. If a control group is present in an experiment, one can be more certain that the independent variable is really responsible for the observations.
The purpose of a control in any experiment is so that you have a natural example to look at at. Ex: If I was doing an experiment on fertilizer, I'd have three different fertilizers and a plant without fertilizer so I could see how it would grow without fertilizer so I could backtrack if need be.
