The Theory and Practice of Item Response Theory PDF ePub eBook

Books Info:

The Theory and Practice of Item Response Theory free pdf Item response theory (IRT) is a latent variable modeling approach used to minimize bias and optimize the measurement power of educational and psychological tests and other psychometric applications. Designed for advanced students, researchers, and psychometric professionals, 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 are applied with the help of widely available software packages. The chapters follow a consistent format and build sequentially, taking the reader from model development through the fit analysis and interpretation phases that one would perform in practice. The use of common empirical data sets across the chapters facilitates understanding of the various models and how they relate to one another.
