The quiz consisted of 30 integrationproblems of varying difficulty. Students were to do as many aspossible in 30 minutes. The 24 students taking the examclosed-notes got an average of 15 problems correct with a standarddeviation of 2.5. The open-notes crowd got an average of 12.5correct with a standard deviation of 3.5.
