Targeted sample size of 50 was calculated based on a power analysis for the above repeated measures analysis using G*Power 3.1 software, estimating a medium effect size, α = .05, power = 0.8, two groups, two measurements, correlation between measures = 0.5, and nonsphericity correction = 1.
Raw correlations were corrected for attenuation resulting from unreliability, which provides an estimate of the correlation between measures should this form of measurement error be reduced [ 52].> -wrap-foot> * p < .05; ** p < .01 Statistically significant correlations between SJT score and personality dimensions ranged from.16 to.36 and.22 to.53 after correction for attenuation.
Data from Farias and colleagues [ 64, 65] support distinguishing between measurement of daily living skills and measurement of neuropsychological functioning, based on data showing a moderate correlation between measures of each in a sample with AD (see also [ 66]).
The study provides evidence of correlation between measures of common ownership and lower output.
Indeed, the correlation between measures of fathers' and sons' antisocial behaviour appears to be about as high as the correlation between measures of antisocial behaviour taken at two points in the life course of the same individual.
But they did find a correlation between measures of happiness and hosting sporting events.
We corrected the pooled standard deviation used to calculate d for the correlation between measures (Dunlap et al. 1996).
n=frac{lambda_{df;alpha; 1-beta }}{frac{varOmega^2}{1-{varOmega}^2}}cdot frac{1-r}{p}=frac{9.63}{frac{0.06}{1-0.06}}cdot }{1-0.06}}cdot=20.1 n, number of participants; λ, noncentral parameter defining skewness and kurtosis of the alternative hypothesis distribution; α = 0.05; β = 0.80; Ω2, effect size; r, correlation between measures; p, number of repeated measures.

In our data, we did not find any correlation between measures from different tests.
Note that we did not include measures of lifetime reproductive success (e.g. total number of pups per lifetime) because such measures could lead to a confusion of effect and cause: long-lived females have more time to produce offspring, almost necessarily creating a positive correlation between measures of lifetime reproductive success and longevity.
