counterbalancing

n. arranging a series of experimental conditions or treatments in such a way as to minimize the influence of extraneous factors, such as practice or fatigue, on experimental results. In other words, counterbalancing is an attempt to reduce or avoid carryover effects and order effects. A simple form of counterbalancing would be to administer experimental conditions in the order A-B to half of the participants and in the order B-A to the other half; a Latin square would be a more complex form.
