Taking all things together, how satisfied are you with your life these days? Please answer with the help of this scale. For instance, when you are totally satisfied with your life, please tick '10'. When you are totally unsatisfied with your life, please tick '0'. You may use all values in between to indicate that you are neither totally satisfied nor totally unsatisfied."

Type: test statistic
Computed in Analysis of Covariance (ANCOVA) or in multiple classification analysis (MCA)
Seldom used in happiness research. See excerpted report for further reference.
ECORRELATION RATIO (Elsewhere sometimes called h or ETA)
Type: test statistic
Measurement level: Correlate: nominal or ordinal, Happiness: metric
Range: [0; 1]

Meaning: correlate is accountable for E x 100 % of the variation in happiness.
E = 0 knowledge of the correlate value does not improve the prediction quality of the happiness rating.
E = 1 knowledge of the correlate value enables an exact prediction of the happiness rating
