Introduction to Nonparametric Item Response Theory introduces social science students and researchers to the theory and practice of the highly powerful methods of Nonparametric item response theory (IRT). Anyone who uses or constructs tests or questionnaires for measuring abilities, achievements, personality traits, attitudes or opinions will find Nonparametric IRT useful for designing and improving such measurements. Many data analysis examples are given in the book, and a user-friendly computer program that is used throughout the book for item analysis supports data analysis using Nonparametric IRT.
