The variable you can't control is presumably the one you want to know.

If you know one variable, it could be anything, weight, temperature, mass etc, and you know the result in the experiment, you can work out the missing variable and therefore the result of your experiment.

How many types of variable should be control in an experiment?

Ideally you control all variables except for the variable of interest.


When a scientific experiment is carried out in a controlled setting all variables are kept the same except for the variable.?

When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.

Why is it important to control variables experiment?

It is so that the experiment is a fair test. In order to protect the integrity and / or accuracy of the experiment and its results, you have to be able to control all the variables so that you know exactly why something is happening. If you do not control the variables, then one of them could be the reason for the results, and you won't be sure why you got the results you did.
