On Comparing Two Observed Frequency Counts

Morton Kupperman

Journal of the Royal Statistical Society Series C, 1960, vol. 9, issue 1, 37-42

Abstract: A simplified method of calculating the χ2 statistic for deciding whether or not two sample frequency counts came from the same unspecified population is discussed. An alternative statistic is presented; it is based on information‐theory considerations and has the advantage of being simpler to calculate.
