Abstract

Determining whether statistics on medical school exam are reported accurately or not has recently been an object of focus. Our goal was to find the answer to this same question for exams at our institution. Percent difficulties, discrimination index, and point biserial of each exam question are compiled and reported. These exam statistics were taken over a sample of 26 courses from the Oklahoma State College of Osteopathic Medicine curriculum. The programming software R was used for a graphical exploration of the data. Exam data shows that question difficulty is negatively skewed and that both discrimination index and point biserial are positively skewed. Only point biserial is highly skewed. Kurtosis is also only significant for point biserial. This is significant because we have greater insight as to whether exam questions are well-written, based on how they perform.
