That is simply not true.There are times when a number of factors can have an effect on the outcome of an experiment but it is not possible to conduct the experiment so that only one factor is allowed to vary while all others are controlled.

You may wish to look at "Latin square design" and "Greco-Latin squares" as an introduction to design.
