What is part of an experiment that is not being tested an is used for comparision?

Answer 1

This probably refers to the 'control'. In a very simple experiment you may add food colouring to a solution to see what colour it sent the solution. You would also have a second sample of the solution which you would not add food colouring to. This would be your control and would serve the purpose of making sure that the solution wouldn't have changed colour by itself anyway. It would also be there for comparison, so that you could compare the colours to see just how much the colour had changed.

Answer 2

Controlled Variable

Answer 3

Those are known as the control groups. They are the group of the experiment that is not manipulated or tested on in any way as to judge the results to. Controls are not necessary for every experiment, but they can prove to be extremely useful.

Answer 4

The control. This may be a group of subjects if one is testing pharmaceuticals, that do not receive the actual test drug. Another example, in a lab experiment to see what happens when water is heated, you would have a control of a container of the same amount of water to which no heat is applied. Then you have the unheated water to compare to the heated water to make observations of.
