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…
Wilcoxon秩和检验(rank-sum test),有时也叫Mann-Whitney U检验,是另一类非参数检验方法,它们不对数据分布作特殊假设,因而能适用于更复杂的数据分布情况。 适用性 (1)资料的总体分布类型未知; (2)资料的总体分布类型已知,但不符合正态分布; (3)某些变量可能无法精确测量; ...

The Wilcoxon rank sum test is equivalent to the Mann-Whitney U-test. The Mann-Whitney U-test is a nonparametric test for equality of population medians of two independent samplesXandY. The Mann-Whitney U-test statistic,U, is the number of times ayprecedes anxin an ordered arrangement of the...
ranks assigned to each group is the test statistic T0. The critical value for T0 for small groups (n = 10) can be found in specific tables. If both groups have n = 10, the distribution is close to normal, and the value of T0 produced can be evaluated using the normal curve table....
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 ...
