The variable factor is the factor you are actually testing. In an experiment, you try to keep all factors constant except the factor you are testing, which is variable.
For example, if you were testing the effect of different dosages of a drug on rats, you would want to keep all the rats in the same room, at the same temperature, with the same lighting, in the same type of cages, being fed the same amount of the same food, etc. That way if there is a change in effect when you vary the dosage, you can reasonably expect that the change in effect is actually due to the change in dosage. If you gave two rats different dosages, but also kept them at different temperatures, then you wouldn't know for sure whether the change in effect was due to the change in dosage or the change in temperature, because you would have two variables.
