A researcher wants to test how feedback type and task difficulty affect persistence on a problem-solving task. 60 participants are randomly assigned to receive either positive or negative feedback throughout the study. Each participant then completes problem sets at three difficulty levels (easy, medium, and hard) in counterbalanced order across separate sessions. Persistence is measured as the time spent on each problem before giving up, in seconds.
