Rating scale analysis
Benjamin D. Wright and Geofferey N. Masters
This book is a text about constructing variables and making measures. The basis is the measurement philosophy of G. Rasch. The text begins by outlining the essentials for measurement, examining data and developing models for measuring, and covers estimation procedures, verifying variables and supervising measures. The authors extend Rasch item analysis and person measurement to attitude questionnaires, performance ratings and other ordered category data.
