Welcome to the SAGE edge site for Psychometrics, Fourth Edition!
In Psychometrics: An Introduction, author R. Michael Furr centers his presentation of material around a conceptual understanding of psychometric core issues, such as scales, reliability, and validity. The focus of this text is on purpose rather than procedure, the "why" rather than the "how to." By emphasizing concepts, logic, and practical applications over mathematical proofs, this book gives students an appreciation of how measurement problems can be addressed and why it is important to address them. Topics are presented accessibly using a wide variety of examples from behavioral science research so readers can see the importance of psychometric fundamentals in research. The fully-revised Fourth Edition now includes technical appendices in R software for relevant chapters, more than twice as many figures and tables to assist in the clarity of the presentation of information, and significant updates to the chapter text including edits for clarity, additional explanations of basic statistics and concepts, and new examples and references throughout.
This site features an array of free resources you can access anytime, anywhere.
