Statistical and Graphical Analysis of Exam Raw Data

Research output: Contribution to conferencePosterpeer-review


Background: Medical students take many examinations during their first two years, thus analyzing exam performance by Course Directors is critical to make sure students perform as expected on exams, and that the exams were written well. Currently, the exam reports from ExamSoft offer detailed performance raw data. We sought to provide professors at OSU-CHS College of Osteopathic Medicine tools for exploratory analysis coupled with graphical visualization for a more informative evaluation of exam performance data.

Methods & Results: Data was taken from a previous exam administered at OSU-COM and uploaded to the R Studio program to generate code for analysis. The code created allows for statistical analysis of the exam, further broken down by each exam writer, allowing for an in-depth analysis. Furthermore, a tool was created allowing for a certain Percent Correct criterion to be set at the discretion of the course director to extract questions below that criterion. This eliminates human error when viewing these questions, and easily marks questions that may need revision.

Conclusion: With these tools, professors will be able to analyze their exams in more depth, allowing for continual improvement of exams administered at Oklahoma State College of Osteopathic Medicine.
