Scale Development - Robert F. DeVellis - Bog

This book presents complex concepts in a way that helps students to understand the logic underlying the creation, use, and evaluation of measurement instruments, and to develop a more intuitive feel for how scales work.

Scale Development: Theory and Applications, by Robert F. DeVellis and new co-author Carolyn T. Thorpe, demystifies measurement by emphasizing a logical rather than strictly mathematical understanding of concepts. The Fifth Edition includes a new chapter that lays out the key concepts that distinguish indices from scales.
