5. Scaling and Dimensionality
The text moves into the geometry of tests, introducing Factor Analysis as the primary tool for understanding the structure of psychological constructs. psychometric theory nunnally pdf
At the heart of Nunnally’s work is a systematic approach to evaluating the "goodness" of a test through two primary lenses: Reliability The Quest for Reliable Measurements 5
Jum C. Nunnally’s Psychometric Theory is considered a foundational "Citation Classic" in the behavioral sciences, specifically designed to bridge the gap between highly technical journal methods and the practical needs of graduate researchers. The text is most famous for establishing rigorous standards for measuring latent traits Scale Development: Theory and Applications by Robert F
- Scale Development: Theory and Applications by Robert F. DeVellis (A "Nunnally-lite" for beginners).
- Foundations of Measurement by Suppes, Krantz, et al. (More mathematical).
- Handbook of Test Development by Downing & Haladyna (Practical applications).
Bottom Line:
As a reference PDF for CTT and reliability, it’s a 4.5/5 star classic. As a modern psychometric textbook (replace with DeVellis, Raykov & Marcoulides, or Embretson & Reise), it’s a 2/5 due to age. Keep the PDF on your hard drive for the reliability chapters, but buy a newer book or use current journal articles for validity and IRT.
