CHAPTER 17

Nonparametric Statistics

LEARNING OBJECTIVES

This chapter presents several nonparametric statistics that can be used to analyze data, thereby enabling you to:

  1. Use both the small-sample and large-sample runs tests to determine whether the order of observations in a sample is random.
  2. Use both the small-sample and large-sample cases of the Mann-Whitney U test to determine if there is a difference in two independent populations.
  3. Use both the small-sample and large-sample cases of the Wilcoxon matched-pairs signed rank test to compare the difference in two related samples.
  4. Use the Kruskal-Wallis test to determine whether samples come from the same or different populations.
  5. Use the Friedman test to determine whether different treatment levels come from the same population when a blocking variable is available.
  6. Use Spearman's rank correlation to analyze the degree of association of two variables.
