| MW | WILCOXON (MANN-WHITNEY) TWO SAMPLE TEST Type: statistical procedure. Measurement level: Correlate: dichotomous, Happiness: ordinal Symbol test statistic: W (Wilcoxon) or U (Mann-Whitney). Relationship: W = U + ½n1(n1 + 1), where n1 and n2 = Ne - n1 , while n1 <= n2, are the sizes of the two samples. Range U [ 0; n1n2 ] and W [ ½n1(n1 + 1); ½n1(n1+ 2n2 +1]. Meaning: At the limit values of U and W there is the strongest possible association. U = ½n1n2 <-> W = ½ n1(Ne + 1) « no association. |
