Скачать или смотреть Chapter 10: Nonparametric Tests

When your data doesn’t meet the assumptions of normality or the sample size is small, nonparametric tests are your solution. In Chapter 10, we introduce the Mann–Whitney U test, Wilcoxon signed-rank test, and Kruskal–Wallis test, powerful tools for analyzing skewed or ordinal data. Learn how these tests work using ranked data, and when to use them instead of traditional parametric methods. Based on Essentials of Biostatistics in Public Health (3rd ed.) by Lisa M. Sullivan.

🎓 Ideal for MPH students, analysts, and anyone working with non-normal data.
