Quizplus · Accepted Answer

Order effects refer to the possibility that the order in which treatments are given in a repeated-measures experiment may influence participants' scores in the second treatment. This can happen because participants may learn or become fatigued, for example, during the first treatment, which could affect their performance in the second treatment. Individual differences, homogeneity of variance, and bi-treatment effects are not specifically related to this type of problem.
