What is Difficulty and Discrimination Index Guide about?
The document provides tables to interpret difficulty index (p), discrimination index (d), and guidelines for evaluating test items based on p and d values. It then provides examples of using the tables to interpret item analysis results. For item 10 with p=0.45 and d=0.37, the suggested action is to revise or improve the item since it is moderately difficult and moderately discriminating. The tables are used to interpret other sample items and determine appropriate actions.
