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
