Correlation Quote by Daniel Kahneman
““could have had a skiing accident during adolescence that left her slightly impaired, and so on. Recall that the correlation between two measures—in the present case reading age and GPA—is equal to the proportion of shared factors among their determinants. What is your best guess about that proportion? My most optimistic guess is about 30%.””
About This Quote
