A-BB-u-mq-v-3-e | r=+.37 p < .01 | Happiness by job performance |

A-BB-u-mq-v-3-e | Beta=+.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

Symbol | Explanation |

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. |

r | PRODUCT-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. |
