The correlation between the biology rank based on my “quality score” and the biology rank based on US News graduate edition is .65 (moderately high) and it is statistically significant at the point zero one level with 19 pairs of scores. The US News rank is not the published rank but the rank from one to nineteen within this list based on the US News published rank.</p>
<p>The correlation between my “quality score” and overall SAT 75th percentile was -.35, not statistically significant.</p>
<p>The correlation between the US News rank (1-19) and total undergrad enrollment was -.19. Between US News rank (1-19) and the number of bachelors grads was -.68. So, my quality score did not do any better at predicting the US News rank than did the number of bachelors degrees awarded, at least within this pool of very large public universities. However, I think the “quality score” would excel when the enrollment sizes varied more widely.</p>

The LAC “quality scores” in post #39 are on a somewhat different scale than post #51 because, for the large publics, the total undergrad enrollment denominator in the ratio for the large publics included their schools of engineering, communications, and so on. It was not just the undergrad enrollment in arts and sciences. This would have made the ratios smaller for the large publics and their quality scores lower relative to the LACs.</p>
