So I thought about colleges that don't award any graduate degrees, and selected the 511 from the list of over 7,000 in IPEDS. These institutions are both public and private, not for profit, and they are in almost every state. Beyond that, though, you get an interesting look at the wide range of diversity in the group via Box and Whisker Charts. If you don't know how to read a box plot, take a quick look at this article, or just know that each dot represents an institution, placed higher or lower on the chart based on the value shown; 50% of the points on the chart are contained within the gray box, 25% are above the top of it, and 25% are below the bottom of it.
Use the filters to include other types of colleges (but be warned, many have not-so-great data) or regions or control.
