Student Faculty Ratios...as simple as they seem?

<p>I would like to go to a college with small, personal classes. Is there anything wrong with my logic that colleges with lower student to faculty ratios have smaller classes (less students in the classes), and a more personalized education? It seems like there are always quirks in the system that I have overlooked...</p>

<p>Specifically I'm looking at:
University of Chicago (4:1)
Carleton College (9:1)</p>

<p>UC has a med school and a larger grad school. Many of those profs never teach ugs. All Carleton profs do.</p>

<p>USNews publishes some information on class size, and the common data sets have more. Since universities have graduate and professional students, and faculty who spend a large amount of their time on research, it is rarely meaningful to compare student faculty ratios of uni's to those of LAC's.</p>
