Overview

This course is intended for researchers and analysts who deal with data that include ratings from human judges. You will learn how to assess whether raters function (as desired) interchangeably, or if they differ systematically in ways that can impair the overall rating system.

Learning Outcomes

Students who complete this course will learn basic concepts of software installation and operation required for Rasch measurements. You will explore fit analysis and measurement models, how to account for estimations and interactions, and anchoring.

  • Define facets, elements, persons, items, raters in the Rasch context
  • Conduct two-facet and three-facet analyses
  • Deal with missing data and bias
  • Handle interactions with dummy facets
  • Detect subsets and determine remedies

Who Should Take This Course

Researchers and analysts in education, psychology, medicine and other fields who deal with data that include ratings from human judges.
