Operationalization
% of time reading books for pleasure when beeped
Remarks
Participants were beeped at random moments eight times 
a day from 7:30 am to 10:30 pm for one week. At each 
beep they answered questions about:
a: what activity they where doing on the moment
b: whom they were with 
c: how they felt at that moment (various feelings, one 
of which happiness)

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.
t.t-STATISTIC (Student's t-statistic)
Type: symmetric standard test statistic.
One parameter: n (= number of degrees of freedom (df) ; range df: [1; + infinite)
Range for t: unlimited

Meaning : the test statistic is the ratio of a difference between a statistic and its expected value under the null hypothesis and its (estimated) standard error with n degrees of freedom.
The critical values of its probability distribution are tabulated extensively in almost any textbook on Statistics.
