Estimating Moments of Universe Scores and Associated Standard Errors in Multiple Matrix Sampling for All Item-Scoring Procedures

Pandey, Tej N.; Shoemaker, David M.

Educational and Psychological Measurement, 35, 3, 567-81, Aut 75

Described herein are formulas and computational procedures for estimating the mean and second through fourth central moments of universe scores through multiple matrix sampling. Additionally, procedures are given for approximating the standard error associated with each estimate. All procedures are applicable when items are scored either dichotomously or polychotomously.
