  • Mann-Whitney U-Test

    • The Mann–Whitney $U$-test is a non-parametric test of the null hypothesis that two populations are the same against an alternative hypothesis.
    • In reporting the results of a Mann–Whitney test, it is important to state:
    • a measure of the central tendencies of the two groups (means or medians; since the Mann–Whitney is an ordinal test, medians are usually recommended)
    • As it compares the sums of ranks, the Mann–Whitney test is less likely than the $t$-test to spuriously indicate significance because of the presence of outliers (i.e., Mann–Whitney is more robust).
    • Overall, the robustness makes Mann-Whitney more widely applicable than the $t$-test.

  • Rank Randomization: Two Conditions (Mann-Whitney U, Wilcoxon Rank Sum)

    • The two most common are the Mann-Whitney U test and the Wilcoxon Rank Sum Test.

  • A Market Society

    • Eli Whitney's invention, the cotton gin, helped to establish the new significance of the market to American society, as it enabled southern planters to reap tremendous profits from cotton exports.

  • Movement South and Westward

  • Kruskal-Wallis H-Test

    • It is an extension of the Mann–Whitney $U$ test to 3 or more groups.
    • The Mann-Whitney would help analyze the specific sample pairs for significant differences.
