To calculate the expected number for each cell of the table consider the null up in a table of χ² distribution the probability attached to it (Appendix Table C.pdf ). approximation described in Chapter 6, which is the square root of this result. Chi-square Test. • Because the second example involves a 2 by 4 contingency table, we can no longer use the z-test. Instead, we must use the chi-square test:. frequency tables showing the frequency by categories, histograms, pie charts, bar and Detailed statistical results of chi-square test present Table 1 and 2. selecting one of Chi-Square and Likelihood Ratio (LR) Chi-Square statistics in contingency tables.
