This step-by-step approach allows students to master testing and measurement concepts through practical exercises and feedback. Using humor, cartoons and real-world examples, Sharon E. Robinson Kurpius and Mary E. Stafford guide the reader through the essential components of measurement, starting with measurement scales and ending with reliability and validity. The authors show that everyone can learn testing and measurement concepts, and they make the learning process fun and non-threatening. For those who want to challenge themselves beyond the self-instructional exercises included throughout each chapter, data sets are provided as an aid to further learning. The book is invaluable for all introductory courses in measurement and testing at undergraduate and lower-level graduate level in the social and behavioral sciences.
