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.
Controlled Variable
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.
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.
The part of the experiment used for comparison and that is not tested is called the control.
The part of an experiment that is not being tested is known as the 'control.'
The control group is the part of the experiment that is being used for comparison. The control group may have no intervention, or may have typical treatment.
the answer is CONTROL
Control.
hi
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.
independent variable
The variable of the experiment that is being tested or the part that is changed by the person doing the experiment is called the independent variable... Thank you for letting me answer goodbye... ;)
== ==
The independent variable is the part of the experiment that is being tested or the part that is changed by the person doing the experiment. The dependent variable is the part of the experiment that is affected by the independent variable.
