Quizplus · Accepted Answer

Millie controls for order effects by randomizing the use of the two strategies. Order effects can occur when the order in which treatments or strategies are applied affects the outcome. By randomly alternating between the two approaches, Millie can help ensure that any changes in behavior are not simply due to the order in which she used the strategies. She may also be controlling for other threats depending on the specific details of the study, but order effects is the only threat mentioned in the given scenario. Selection effects relate to the characteristics of the participants or groups being studied, treatment effects relate to the effects of the treatment or intervention being used, and history effects relate to external events occurring during the study period.
