Assessment Exam - Item Analysis-Reports on Discrimination Index

Video Transcription

Video Summary

This video explains how to analyze and evaluate discrimination index in exams using a question report feature. The discrimination index helps identify questions that are poorly written or biased. By running a histogram on the 2019 exam, the video demonstrates how to visually analyze the distribution of questions based on their discrimination index. It shows that there are both high and low discrimination questions, with negative discrimination suggesting that good students answer wrongly more often than bad students. Using Oasis, the video highlights the ability to identify the authors of questions with low or high discrimination, allowing for informed decisions on inviting certain authors for future question writing.
