C-BW-c-sq-l-10-caSelfreport on single question:

Here is a picture of a ladder. Suppose we say that the top of the ladder (9) represents the best possible life for you and the bottom (0) represents the worst possible life for you. Where on the ladder do you feel personally stand at the present time?
[ 9 ] best possible life for you
[ 8 ]
[ 7 ]
[ 6 ]
[ 5 ]
[ 4 ]
[ 3 ]
[ 2 ]
[ 1 ]
[ 0 ] worst possible life for you

Name: Cantril's self anchoring ladder rating of life (adapted version)


Appendix 2: Statistics used
SymbolExplanation
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.
