SymbolExplanation
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.
