Quizplus · Accepted Answer

By using three different groups of participants, Kendra will not have to worry about attrition, which refers to participants dropping out of the study over time. With a repeated measures design where the same participants are exposed to multiple conditions, attrition can be a problem as participants may become disengaged or otherwise unable to continue with the study. With three different groups of participants, attrition is less likely to have an impact on the results.
