A causal-comparative design is a research design that seeks to find relationships between independent and dependent variables after an action or event has already occurred. One could then use the Mann-Whitney-Wilcoxon (M-W-W) test or other nonparametric two-sample method based on these mid-ranks to compare the two groups in terms of the level of the analyte. This book offers a new, fairly efficient, and robust alternative to analyzing multivariate data.

The Kruskal–Wallis test by ranks, Kruskal–Wallis H test (named after William Kruskal and W. Allen Wallis), or one-way ANOVA on ranks is a non-parametric method for testing whether samples originate from the same distribution. Kruskal-Wallis test, proposed by Kruskal and Wallis in 1952, is a nonparametric method for testing whether samples are originated from the same distribution. Non parametric counterparts are Wilcoxon (Mann-Whitney) and Kruskal- Wallis respectively. The Mann-Whitney U test is another powerful nonparametric test. It provides an easier syntax to generate information-rich plots for statistical analysis of continuous (violin plots, scatterplots, histograms, dot plots, dot-and-whisker plots) or categorical (pie and bar charts) data.
