The proposition that human attributes are measurable remains controversial, as do the ideas and innovations of the six historical figures-Gustav Fechner, Francis Galton, Alfred Binet, Charles Spearman, Louis Thurstone, and S. S. Stevens-at the heart of this book. Across10 rich, elaborative chapters, readers are introduced to the origins of educational and psychological scaling, mental testing, classical test theory, factor analysis, and diagnostic classification and to controversies spanning the quantity objection, the role of measurement in promoting eugenics, theories of intelligence, the measurement of attitudes, and beyond.
Graduate students, researchers, and professionals in educational measurement and psychometrics will emerge with a deeper appreciation for both the challenges and the affordances of measurement in quantitative research.
