* Multiple selection items (“choose all that apply”)
¹ p - Difficulty index: number of correct responses / total number of responses – higher number means easier item
² D - Discrimination index (generalized ULI): difference in ratio of correct answers in upper and lower third of students
³Evaluation cutoffs for discrimination index [100]: >.40 Very good (++); .30–.39 Reasonably good (+); .20–.29 Marginal (−), <.19 Poor (− −)
⁴ Percentage of students choosing option – correct options are bolded
