Question

Quizplus · Accepted Answer

Counterbalancing is used to distribute progressive error (such as fatigue or practice effects) across different treatment conditions in within-subjects designs, rather than eliminating it entirely. This helps ensure that such errors do not systematically bias the results in favor of one condition over another.
