An equation is derived which expresses test reliability as a function of number of item alternatives for the case in which only error due to guessing is present. This result is compared with the modified Spearman-Brown equation given by H. H. Remmers and his associates. Reliability coefficients predicted by these equations are compared with coefficients generated by a computer simulation method
