Controlling for a variable is the act of deliberately varying the experimental conditions in order to take a single variable into account in the prediction of the outcome variable. Controlling tends to reduce the experimental error. A control is something that does not change in the experiment.
In an experiment, variables that are not changed are called control variables. These variables are kept constant to ensure that any changes observed in the experiment are due to the manipulated variable, or independent variable, and not due to other factors.

The control
Variables that remain constant in a scientific experiment are called controlled variables. These variables are not changed throughout the experiment to ensure that any observed effects are due to the independent variable being tested.
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.
These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.
They shouldn't, ever. It defies the whole point of a controlled experiment.
It depends on the experiment or the category. you welcome s.a No it's the variable k.a.
by the variables. The variables are manipulated and responding. the manipulated ones are the one that is changed in the experiment. the responding variable is the one who is expected to change.

A scientific experiment must be done by something that can show change. All of these can be variables.
