Why do the rankings from U.S. News & World Report list some schools twice? The 2014 rankings of US statistics doctoral programs compiled by the U.S. News &amp; World Report lists a few of the schools twice. I assume that the rankings are probably for different types of statistics programs (Harvard for example has both a statistics department but also a very good School of Public Health, which I'm sure has a biostatistics program), but the methodology section does not address this problem and I am doing research which requires analysis of this list.

Question:  Why are some schools listed twice in the rankings?

I cannot request this information from U.S. News &amp; World Report directly because they only release this information to university officials.
If you click on a school's name, you can see the rankings of its various departments, including both Statistics and Biostatistics if applicable (example). This is pretty inconvenient, as it requires going through the schools one-by-one, but I'm not sure there's a better way to get that information.

There is also a post on gradcafe separating the rankings, though I'm not sure if it includes the entire list.
