Univariate techniques are used for analyzing one variable at a time. When the data is nonmetric, the appropriate tests are chi-square, Mann-Whitney, Median, K-S, and K-W one-way ANOVA. Chi-square is used to test the independence of two categorical variables. Mann-Whitney is used to compare two independent groups on a non-metric variable. Median is used to test the difference between two medians of non-metric variables. K-S test is used to examine whether two samples come from the same distribution. K-W one-way ANOVA is used to test for significant differences between two or more independent groups of non-metric variables. Therefore, the best choice is B - two independent samples, as it can be analyzed using Mann-Whitney, K-S, and chi-square tests.
