Hello,
With Jamovi, the One Sample T-Test (non parametric) is called ‘Mann-Whitney U’. The displayed statistic is a sum of ranks ($T^{+}$).
The Paired Samples T-Test (non-parametric) is called the ‘Wilcoxon rank’. The displayed statistic is a sum of ranks ($T^{+}$).
The Independent Samples T-Test (non-parametric) is called the ‘Mann-Whitney U’. The displayed statistic is a sum of comparisons that is calculated from a sum of ranks:
$$U_{1}= n_{1}\cdot n_{2}+ \frac{n_{1}(n_{1}+1)}{2} - T_{1}$$
For the sake of consistency, I suggest that the One Sample T-Test (non-parametric) would be renamed ‘Wilcoxon rank’.
Hoping that my remark is understandable, I send you my best regards.

[RESOLVED] Denomination of non parametric tests
Re: Denomination of non parametric tests
well this is a bit embarrassing.
you're quite right. i'm surprised this escaped our attention for so long.
will be fixed in the next version.
with thanks
