Appendix 2: Statistics used
SymbolExplanation
dCohen's COEFFICIENT FOR GROUP DIFFERENCES. Also called EFFECT SIZE
Type: descriptive statistic only
Measurement level: Correlate : dichotomous, Happiness level: metric
Theoretical range: unlimited.

Meaning: effect size indicator for difference of means.
Formula: Cohen's d = (M2 - M1) ? SDpooled
SDpooled = ?((SD1^2 + SD2^2) ? 2)
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.
rPRODUCT-MOMENT CORRELATION COEFFICIENT (Also "Pearson's correlation coefficient' or simply 'correlation coefficient')
Type: test statistic.
Measurement level: Correlate: metric, Happiness: metric
Range: [-1; +1]

Meaning:
r = 0 no correlation ,
r = 1 perfect correlation, where high correlate values correspond with high happiness values, and
r = -1 perfect correlation, where high correlate values correspond with low happiness values.
