I have read about Wilcoxon–Mann–Whitney and Nemenyi tests as "post hoc" tests after Kruskal Wallis.

Why is it faster to reheat something than it is to cook it? For example, if you want to plot gene expression of difference disease states (pre-treatment, post-treatment), you'll get post-treatment first.
