Question

Quizplus · Accepted Answer

Counterbalancing is used to control for the effects of the order in which conditions are experienced. By having participants start with different conditions and eventually exposing all participants to all conditions, Dr. Tran is ensuring that any order effects are distributed across the conditions rather than confounding the results. This method helps to mitigate the impact of practice effects (improvement due to repeated testing) and carryover effects (residual effects of previous conditions) by varying the order in which conditions are presented.
