If we want to perform a two-tailed test for differences between two populations of nominal data with exactly two categories, we can employ either the z test of , or the chi-square test of homogeneity, since squaring the value of the z statistic yields the value of statistics.

Quizplus · Accepted Answer

This is true. The z test and chi-square test of homogeneity can both be used for a two-tailed test of differences between two populations of nominal data with exactly two categories. Squaring the value of the z statistic yields the value of the chi-square statistic.
