A chi-square test for independence is appropriate for comparing non-numerical data in a differential design when comparing samples representing two populations. This test allows for evaluating whether there is a significant association or relationship between the two samples. The t-test and analysis of variance are appropriate for comparing numerical data, while the repeated-measures t-test is used for comparing data in which each subject is measured at two different time points.
