A Test Theory Model for Ordinal Measurements

Schulman, Robert S.; Haden, Richard L.

Psychometrika, 40, 4, 455-72, Dec 75

A model is proposed for the description of ordinal test scores based on the definition of true score as expected rank; its deviations are compared with results from classical test theory. An unbiased estimator of population true score from sample data is calculated. Score variance and population reliability are examined. (Author/BJG)
