Type: test statistic.
Measurement level: Correlate: metric, Happiness: metric
Range: [-1; +1]

O-HL-u-sq-v-3-z

Beta = +.26 ns

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.
