- How to report the results of the Mann-Whitney U Test? We adhere to the APA style guidelines.
A Mann-Whitney U test tests whether there is a difference between two independent samples. But how to report the Mann-Whitney U Test?
Reporting the results of the Mann-Whitney U test according to APA style requires presenting key statistics and findings in a clear, concise manner.
Here's a general guideline on how to report the results in 6 steps!
- Specify the test and purpose
- Report the U statistic
- Report the Significance Level:
- Sample Size
- Effect Size
- Summarize the Results

wait, what about reporting the mean-rank or median? one should have to report the very statistics being compared, right?
In Datatab, I very frequently use the Mann-Whitney U-test. Now I wonder how to correctly interpret the measured effect size r. For the t-test, a table is shown in Datatab, for help on interpreting the value of d (the t-test effect size).
Is there a comparable table for r (the effect size of the Mann-Whitney U-test)?
Hi, thanks for your comment! Please have a look here at the end of the tutorial datatab.net/tutorial/mann-whitney-u-test
@@datatab Thank you! That is really a great help! 🙏 Until now I have fruitlessly searched the literature for these specific data. And maybe would it be possible to include the table in the statistics calculator if one clicks the button for Effect size?
@@ewald59 Yes that is a good point! I will have a look at it! In many tests, however, the effect size has moved directly to the bottom of the results table and there is sometimes no longer a button with "Effect Size".
@@datatab that would be an excellent spot too!
@@datatab Thank you so much for adding the effect size table to the Mann-Whitney U-test Summary in words!
