The appropriate way to test differences in proportions for more than two samples is to use the cross-tabulation procedure to conduct a chi-square test. This method allows for the comparison of counts between multiple categories and can determine whether there is a statistically significant difference in proportions across the samples. Other methods such as t-tests or z-tests are not appropriate for comparing proportions.
