How To... Perform a Wilcoxon Signed Rank Test (By Hand)

The Wilcoxon Signed Rank Test is a non-parametric test for comparing two paired (dependent) data sets. It is an alternative to Students Paired t-Test and is used when one or more of the data sets is not normally distributed, and sometimes when sample siz is small.

Data source: Laureysens et al (2004).

I remember the first time I ever learned about a Wilcoxon test, my buddy called it a Willcocksuckin test. I laughed hysterically.
