Quizplus · Accepted Answer

The experiment used a between-subjects factorial design, as there were two independent variables (intentionality and stability of request) that each had two levels (unintentional vs attentional and always vs sometimes, respectively), resulting in four conditions (unintentional/always, unintentional/sometimes, attentional/always, attentional/sometimes). Each participant only received one request from one needy student, so there was no within-subjects manipulation.
