Exams are used to measure student progress and subject mastery. Exam item performance
can be assessed by Item Difficulty, Discrimination Index (DI), and Point Biserial
(PB). A previous investigation descriptively characterized these metrics for 62 exams
at the Oklahoma State University College of Osteopathic Medicine, however, the distribution
characteristics remain unknown. The primary objective of this study was to determine
the normality of the item Difficulty, DI, and PB for these 62 exams.
