Appendix 2: Statistics used
SymbolExplanation
GGOODMAN & Kruskal's GAMMA
Type: test statistic
Measurement level: Correlate: ordinal, Happinessl: ordinal
Range: [-1; +1]

Meaning:
G = 0 no rank correlation
G = +1 strongest possible rank correlation, where high correlate values correspond to high happiness ratings.
G = -1 strongest possible rank correlation, where high correlate values correspond with low happiness ratings.
tauGOODMAN & Kruskal's TAU
Type: descriptive statistic only.
Measurement level: Correlate: nominal, Happiness: ordinal
Range: [0; +1]

Meaning:
tau = 0 knowledge of the correlate value does not improve the prediction quality of the happiness rating.
tau = 1 knowledge of the correlate value enables a perfect (error-free) prediction of the happiness rating.
