jamovi

Hi, Paul, thank you for your renewed feedback. I wonder why jamovi outputs the biserial rank correlation coefficient as effect size for the Wilcoxon Signed Rank Test. First, because there is hardly any information (as you wrote yourself) on how to interpret it. And to have an effect size of which on...

Hi Paul, thanks a lot for your response. I read the article too. However, it is still unclear to me how to interpret the strength of the effect (how strong is the effect for example at a value of 0.3 or o.9). Can you refer to a source in this regard? In addition, it is still unclear to me why the pe...

Furthermore I read that biserial rank correlation is used in the presence of a dichotomous variable, which in my case (per-post test with Interval scaled) is not given..

Hey, Jonathon, thank you for your feedback and explanations. All right, I understand... Then who can I contact to answer my questions? I don´t want to report something without fully understanding it myself. I've already read through the link you sent. Here, however, it's not clear how the effect siz...

...respectively I am wondering why jamovi is using biserial rank correlation instead of Pearson´s product-moment-correlation.

Do you have any Information about that?

Hey Jonathon, thank you for your message which I unfortunaltely have not noticed and read until an hour ago. Cool, you added an effect size for the Wilcoxon Test! One last question (I hope so)....How do I have to interpret the biserial rank correlation effect size? Is it the same categorization as f...

Hi Jonathon,
thanks a lot for your response!
Cheers,

Hey,
are there any news about the availability of the effect size for the WSR-test?

I´d be very grateful about a short update .

Greetings, Lisa

Hi Jonathon,
thank you for your response!
Ok, cool. So I am waiting for the update .

Hi Jonathon,

how would you report the effect size in this case?

To my knowledge reporting Cohan's d in the context of Wilcoxon signed rank test is not correct.

I'd be happy about a short response.
