Hi does anyone have experience of using Wilcoxon signed ranks test in Excel? I know there are some online tools for it and that you can do it in SPSS, Epi Info etc, but I want to create a tool that does it in Excel for practitioners to use to analyse data that has small samples or is not normally distributed, i.e. where a paired sample t test would not be appropriate.
I found a tool here http://udel.edu/~mcdonald/statsignedrank.xls
- if anyone has used it or can vouch for its accuracy that would be great.
Thanks & best wishes
