Assessment Exam - Item Analysis-Item Analysis with Re-Used Questions

Video Transcription

Video Summary

The video discusses the discrimination index and how it can be used to analyze question performance across different types of students. If a question is used in multiple exams, viewers have the option to view normative data for that question, which provides a more detailed analysis of its selection and how the discrimination index behaves across different products. It is noted that only two exams have sufficient data to compute the discrimination index, with a sample size typically representing 27% of all users. The discrimination index may vary for each exam due to different user answers and sample sizes. There are different ways to calculate the discrimination index, including an average or weighted average based on sample size. The OASIS software allows users to analyze and interpret this data subjectively. No credits are given in the transcript.
