Verbal vs. mathematical aptitude in academics

It isn't too difficult to find GRE scores by intended major online. In reviewing articles/posts for my post below on anthropology I noted the distinction made between quant & qual methods, and aversions to regressions and scatter plots (or the supposed love of biological anthropologists for these tools). That got me wondering about the average mathematical and verbal aptitudes of those who intend to pursue graduate work in anthropology. I removed some extraneous disciplines which I don't think add anything, and naturally I created three scatter plots, quantitative score vs. verbal score, writing score vs. verbal score, and writing score vs. quantitative score.
