Preparing Data for and Interpreting Item Analysis

Preparing Data for and Interpreting Item Analysis

The purpose of this activity is to enable the learner to learn how to use item analysis data to refine the quality of faculty written items for classroom tests. Additionally, participants will learn a method to structure single response (e.g. multiple choice, hotspot) and multiple response (e.g. ordered response, multiple select) data for an item analysis process.

Learning Objectives:

  • Participants will learn what item and option statistics can be calculated, how to interpret the statistics to evaluate item performance, and how item statistics and class size (sampling) impact the reliability estimates for exams.
  • Participants will learn how to organize item data for single-select, numeric-response, ordered-response, and multiple-select items for an item analysis of all item types.
  • Participants will take part in presenter-guided item review meetings using their own exam data or example data to learn how to update items based upon item and option statistics.
