In my world a correlation coefficient of 0.12 would be risibly small: we'd just say that the data gave a pudding plot and try to find a different way to measure things. I take it that in Social Science 0.12 isn't bad as long as the confidence interval doesn't span zero? Fair enough, but what use is that coefficient? What does it imply for further work??deariemenoreply@blogger.comtag:blogger.com,1999:blog-4624586630299165335.post-7857030041302282142015-09-20T17:14:25.146+01:002015-09-20T17:14:25.146+01:00What's the correlation between IQ and number o...What's the correlation between IQ and number of children, Doc?
