The rule is quite simple if k is the value on the Mann-Whitney Table, then the critical value for the Wilcoxon Rank-Sum test is k+m(m+1)=2 where m is the smaller of the two samples sizes. E.g. for alpha = .05 and n1 = 10 and n2 = 12, the critical value on the Mann-Wh...
1.引入首先,在alevel FurtherMaths这本书上对于Wilcoxon rank-sum test(WSRT)的阐述留下了很多疑惑,没有很好的展现该test的意义,完整的说明该test的原理,我在这里会给出一个对于该test补充的说明。 2.历史和…
Small sample Tables Tables for the Wilcoxon rank-sum test are given in the Appendix at the end of this module. A segment is printed as Table 1. When the two samples have di?erent sizes, the tables are set up for use with the rank sum for the smaller of the two samples, so that ...

Our test statistic (7) is smaller than the critical value (13), so there is a significant difference in the medians. We can reject the null hypothesis. References Table: http://users.stat.ufl.edu/~winner/tables/wilcox_signrank.pdf ...
Since you use W instead of T and refer to W+ and W- are you using the Wilcoxon Rank Sum Test (instead of the Wilcoxon Signed-Ranks Test, which is what this table refers to)? Charles Reply Samaa October 23, 2020 at 1:23 am ...
An excerpt of the Wilcoxon Rank Sum (Mann-Whitney U) table of critical values for a two-tailed test is shown below: So, the critical value is 64. For the Wilcoxon Rank Sum test, we conclude that there is a significant difference between the groups when the Test Statistics is less than...
