A computer program named Program STANDARD is presented and demonstrated. This program calculates the statistical significance of the overall agreement of the categorical assignments. The program is based on Light's statistic, G, for describing the conjoint agreement of many observers with correct or standard set of classifications on nominal scales. The present documentation includes a description of the program's purposes, input, output, language and processing, limitations and computational formulae. Also provided are instructions for preparing the job deck, a listing of the FORTRAN source deck, order of the card deck for computer processing, and a complete set of sample input and output data.
