A COMPUTER PROGRAM FOR ESTIMATING TRUE-SCORE DISTRIBUTIONS AND GRADUATING OBSERVED-SCORE DISTRIBUTIONS.

Abstract

The program takes a frequency distribution of number-right test scores and produces (1) an estimated distribution of true scores for the group tested, computed on the assumption that the errors of measurement have a certain compound binomial distribution, (2) the corresponding smoothed distribution of actual scores, and (3) a chi-square for comparing the smoothed and the actual distributions. All instructions and background information necessary for practical use of the program are given. (Author)
