The Chi Square Test of No Association in an R x C Table For reasons not detailed here (see Appendix), the comparison of observed and expected counts defined on page 9 is, often, distributed chi square when the null is true. • For one cell, when the null is true, Observed Expected Count - Count Expected Count L NM O QP 2 WebTo calculate the expected numbers a constant multiplier for each sample is obtained by dividing the total of the sample by the grand total for both samples. In table 8.1 for sample A this is 155/289 = 0.5363. This fraction is then successively multiplied by 22, 46, 73, 91, and 57. For sample B the fraction is 134/289 = 0.4636.
