Rating by supervisor:
Overall, how would you rate this employee's performance 
over the past year. Answer rated from 1(poor) to 
5(excellent)

Happiness by job performance
A-BB-u-mq-v-3-eBeta=+.20 p < .01
Beta controlled for:
-positive mood of that day
-negative mood of that day

Addition of happiness in a hierarchical regression 
increases R2 from .08 to .21 Happiness predicts 
performance much better than mood of the day.

Appendix 2: Statistics used
SymbolExplanation
Beta STANDARDIZED REGRESSION COEFFICIENT by LEAST SQUARES (OLS)
Type: test statistic.

Measurement level: Correlates: all metric, Happiness: metric.
Range: [-1 ; +1]

Meaning:
beta > 0 a higher correlate level corresponds to a higher happiness rating on average.
beta < 0 a higher correlate level corresponds to a higher happiness rating on average.
beta = 0 no correlation.
beta = + 1 or -1 perfect correlation.
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.
