Description

Item response theory (IRT) is a latent variable modeling approach used to attenuate bias and optimize the measurement power of educational and psychological tests and other psychometric applications.

Designed for researchers, psychometric professionals, and advanced students, this book clearly presents both the “how-to” and the “why” of IRT. It describes simple and more complex IRT models and shows how they’re applied with the assistance of widely to be had software packages. Chapters follow a consistent format and build sequentially, taking the reader from model development in the course of the fit analysis and interpretation phases that one would perform in practice. Using common empirical data sets around the chapters facilitates figuring out of the quite a lot of models and how they relate to each other.
