Applied Psychometrics Using R Software (Paperback)

Applied Psychometrics Using R Software is a hands on guide for anyone who needs to evaluate the quality of educational, psychological, or survey-based measures with confidence and clarity. Blending accessible theory with practical application, this book walks readers through the essential tools and techniques of modern psychometric practice―always with an eye toward real world use.

Each chapter tackles a core measurement topic, from item analysis and reliability to generalizability theory, validity, scoring, item response theory, equating, and differential item functioning. Concepts are introduced with just enough technical grounding to build understanding, followed by step by step demonstrations in R that show how to implement, interpret, and communicate psychometric analyses in practice.

Designed for researchers, practitioners, and graduate students, this book aims to be the resource that gets pulled off the shelf again and again: the volume handed to a student who needs a clear explanation, the reference that steadily rises to the top of a working researcher’s desk, the companion tucked into a graduate student’s bag on the way to class, the text proudly listed on syllabi, and―on occasion―the coaster beneath a mug of coffee during deep reflection on a stubborn measurement problem.

Whether you are learning psychometric methods for the first time or refining your applied skills, Applied Psychometrics using R Software offers guidance, insight, and a bit of good natured companionship as you navigate the challenges of measurement in the social sciences.
