Appendix 2: Statistics used
Type: statistical procedure.
Measurement level: Correlate: dichotomous, Happiness: ordinal
Symbol test statistic: W (Wilcoxon) or U (Mann-Whitney).
Relationship: W = U + n1(n1 + 1), where n1 and n2 = Ne - n1 , while n1 <= n2, are the sizes of the two samples.
Range U [ 0; n1n2 ] and W [ n1(n1 + 1); n1(n1+ 2n2 +1].

At the limit values of U and W there is the strongest possible association.
U = n1n2 <-> W = n1(Ne + 1) no association.
