When I teach students about the correlation coefficient, I like to give students a sense of how correlations map on to common associations that might be encountered in daily life and across various topics and disciplines.
Some years back I read a psychology journal article (it might have been American Psychologist) that presented a table of meta analytic correlations across a wide range of topics and disciplines (e.g., 40 or 50 correlations from medical, psychological, economic, and other domains). The table aimed to highlight what are typical correlations in a given domain in order to provide context for the interpretation of a correlation coefficient. However, I can't remember the reference for the particular journal article.
- Does anyone know where a general listing of the magnitude of typical correlations across a wide range of disciplines and topics could be obtained?
