Brown, Thomas C.; Daniel, Terry C.; Schroeder, Herbert W.; Brink, Glen E. 1990. An analysis of ratings: a guide to RMRATE. Gen. Tech. Rep. RM-195. Fort Collins, CO: U.S. Department of Agriculture, Forest Service, Rocky Mountain Forest and Range Experiment Station. 40 p.

This report describes RMRATE, a computer program for analyzing rating judgments. RMRATE scales ratings using several scaling procedures, and compares the resulting scale values. The scaling procedures include the median and simple mean, standardized values, scale values based on Thurstone's Law of Categorical Judgment, and regression-based values. RMRATE also computes reliability statistics and analyzes the ratings using principal component analysis techniques to assess variation among judges. RMRATE should be useful to practitioners needing to summarize or analyze rating data, and to researchers interested in comparing and evaluating alternative scaling methods.

Keywords: Ratings, psychological scaling, reliability, judgment scaling model
