Michael Akritas Lecture 29 Chapter 10: Comparing Two Populations Outline Nonparametric Methods Paired Data The RankSum Test Procedure Motivation I The contrastbased procedures require large sample sizes. I The MannWhitneyWilcoxon ranksum test (or ranksum test for short), which will be described, can be used with both small and large sample sizes. Michael Akritas Lecture 29 Chapter 10: Comparing Two Populations Outline Nonparametric Methods Paired Data The RankSum Test Procedure Motivation I The contrastbased procedures require large sample sizes. I The MannWhitneyWilcoxon ranksum test (or ranksum test for short), which will be described, can be used with both small and large sample sizes. I If the two populations are continuous, the null distribution of the TS is known even with very small sample sizes.

I The MannWhitneyWilcoxon ranksum test (or ranksum test for short), which will be described, can be used with both small and large sample sizes. I If the two populations are continuous, the null distribution of the TS is known even with very small sample sizes. I For discrete populations, the null distribution of the TS can be well approximated with much smaller sample sizes than those required by contrastbased procedure.
