Ordinal Item Response Theory

Ordinal Item Response Theory
Mokken Scale Analysis

May 2011 | 128 pages | SAGE Publications, Inc
Measurement in the social sciences often refers to standardized answers to close-ended questions, in which answers are analyzed as if they were measurements on an interval scale. This volume presents a measurement model that maintains the ordinal aspects of the data in order to establish how well the model fits and how it measures subjects and items. It relaxes the most stringent assumptions from parametric item response theory, while maintaining its advantages over classical measurement methods, such as reliability and factor analysis. This volume is less technical than other books on the topic and is ideal for introductory courses in social science measurement.

Key features
  • Provides students with hands-on calculations: The book offers transparency of method that students will appreciate.
  • Help students more easily find structure among a subset of data: The author shows how ordinal item response theory can be the most efficient method for working with scales with only a few items.
  • Compares this method to models for classical test theory such as factor analysis and reliability analysis: This provides students with an alternative that is more applicable to social science research.
