Appendix 2: Statistics used
SymbolExplanation
DMDIFFERENCE of MEANS
Type: descriptive statistic only.
Measurement level: Correlate: dichotomous, Happiness: metric
Range: depending on the happiness rating scale of the author; range symmetric about zero.

Meaning: the difference of the mean happiness, as measured on the author's rating scale, between the two correlate levels.
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.
tcKENDALL'S TAU-C (Also referred to as Stuart's tau-c)
Type: test statistic
Measurement level: Correlate: ordinal, Happiness: ordinal
Range: [-1; +1]

Meaning:
tc = 0 no rank correlation
tc = 1 perfect rank correlation, where high values of the correlate correspond
with high happiness ratings.
tc = -1 perfect rank correlation, where high values of the correlate correspond
with low happiness ratings.
