ExamStat™ is an Online Item Analysis system developed by BYU Testing Services and the BYU Faculty Center. ExamStat works by receiving test information from participating systems or individuals and processing it using well-established methods. Once test information is processed, all instructors associated with the test are notified via e-mail of the availability of a report.
What is Item Analysis?
Item Analysis consists of a statistical exploration of the relationships between overall student scores and the responses given by the individual students. It helps determine item (or question) difficulty, overall test reliability, and other factors.
What are the Benefits of Item Analysis?
The basic premise for a test is to measure student performance. Item Analysis can help teachers do this more effectively by identifying questions that may be confusing, miskeyed, or otherwise likely to produce inaccurate results. Instructors and administrators can then use this information to revise and improve tests.
What Does ExamStat Provide?
ExamStat provides an 8-page analysis which contains overall test results and reliability, item and distractor details, improvement suggestions, and student scores and answers.
How Do I Process Test Data Using ExamStat?
ExamStat provides several ways for individuals or organizations to submit data. The most common ways to submit data are by using ScanTools data files or Tab-Delimited files which can be easily created with a spreadsheet. These files are sent to ExamStat through a simple web-based interface.
