Can anyone direct me to a resource on how to do a two tailed Mann Whitney
statistical test in Excel 2007? Since there is no direct Mann Whitney (AKA
Wilcoxon signed rank test) function that I can find, I guess I need some
instructions on how to take two columns of data and walk through the test
step by step to get a P value.

Thanks.
