Observed Relation with Happiness
O-HL-g-sq-v-3-dG=+.69 p < .05
O-HL-g-sq-v-3-dtau=+.45 p < .05
% very happy
married  41
widow    23
single   22
divorced 19
The relationship remains sizable after control for 
recent financial change, race, household size and 
social participation (memberships, frequency of 
social contacts and visits to bars and taverns). 
The lower happiness of the ex-married is partly 
explained by recent decrease in income. Change in 
average happiness in the USA from 1973 to 1982 can 
partly be explained by a drop in % marrieds and a 
consequent rise in % decrease in income.

Appendix 2: Statistics used
Type: test statistic
Measurement level: Correlate: ordinal, Happinessl: ordinal
Range: [-1; +1]

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]

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.
