Hi all,

First of all let me say what a great job you're doing with jamovi - it's a fantastic tool to teach statistics with. I trialled it with our postgraduate students this year, and we're rolling it out to our undergraduate students this coming academic year.

I have a query about the choice of effect size for running Mann-Whitney or Wilcoxon Signed Ranks analyses - both default to reporting Cohen's d (presumably as they are sub-options in the t-test analyses). However, I was always taught to use r - as in 'Z / sqrt #data points' in the instance of these non-parametric equivalents and this is what we've previously taught students to use when running SPSS.

Is it possible to have this calculated instead of or as well as Cohen's d when selecting the non-parametric option?

Cheers - and keep up the good work!
