Product Review

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. Robert DeVellis demystifies measurement by relating it to familiar experiences and by emphasizing a conceptual rather than a strictly mathematical understanding. Students′ attention is drawn to important concepts that are foundational for subsequent topics, with opportunities provided to test understanding through chapter summaries and exercises.
