CHITRAN - A 7030 (STRETCH COMPUTER PROGRAM FOR THE CHI-SQUARE TEST OF NORMALITY

Abstract

The CHITRAN program computes the Chi-square statistic for testing the hypothesis that a random sample is from a normal population. Also given are the degrees of freedom for the Chi-square statistic, a bar chart (frequency distribution), the mean, standard deviation, range, maximum, and the minimum of the observations comprising the sample. Eleven transformations on the observations are possible before the calculations are performed. An optional feature, 'pooling,' allows the grouping of samples in order to obtain a single Chi-square statistic for the grouped (pooled) data. CHITRAN is written in FORTRAN IV for the IBM 7030 (STRETCH) computer.
