" If you are trying to choose a college, in my opinion it makes more sense to look at the number of earned PhDs adjusted either for school size or for major size."
I think anyone is entitled to believe that. I do NOT, however, think they are entitled to misrepresent data. If they are presenting a table, data or result that represents production PER CAPITA , they should say so, and not call it production without reference to the denominator. Since “production” and “production per capita” are not the same.
IMO you should look at both, along with lots of other things. Then ask questions at the school and apply your brain. Many larger institutions have a larger spread of majors than LACs have. .Also many large institutions enroll a larger spread of capability levels of incoming students.
If you are an entering student with the aptitude and desire to pursue a Phd in environmental engineering you would like to know whether a given institution can likely provide you with helpful training towards that result. If hundreds of students from a given university are achieving that result, evidently the training they got there must have been sufficient towards same. Even if other people at that same university study English literature, nursing, prefer medical school or law school, get recruited at investment banks, or aren’t smart enough to get Phds… Hence watering down the university’s “per capita” number. The issue isn’t what the other people there do, it’s what you personally can accomplish there, given your interests and capabilities.
I say this as a graduate of a university that offered diverse programs of study, and had a diverse student body based on interests, and abilities too, to an extent. Only 1/3 of its students were in its Arts & Sciences College- which is pretty much all that the LACs are. But people are putting that whole university’s student population in the denominator in making these tables, despite differences in interests, majors and abilities of large chunks of its student body compared to "peer"LACs. Even though all those other people’s destinations had nothing to do with my result., as a particular student with my particular set of abilities with a particular major within the Arts & Sciences college there.,
What I observed from there is, the people who were good enough achieved exactly what they should have. Those who wanted to go on to Phds, and were good enough, did. And there were lots of them. Many didn’t want that though. at my school. Many future MDs, MBAs and lawyers. Most went to work, by choice. And the school helped with that, along with helping those pursuing advanced studies. . Other students weren’t good enough. They didn’t do as well. Big shock.
Here’s another opinion I found on the web:
"“Students can increase their odds of being accepted to graduate school if they earn their bachelor’s degree at a liberal arts college. On a per capita basis, for instance, liberal arts colleges produce twice as many students who earn a PhD in science than other institutions.”
"This reasoning has – and always will be – absurd. I attend one of the touted liberal arts institutions that ranks extremely highly in per capita PhDs (I believe we’re the second-highest liberal arts college in the country in per capita PhD rates), and I can say that part of the reason we produce doctorates is because the students here came in with a predisposition for research and less interest (comparatively) in careers after college.
Presupposing that per capita PhD rates NECESSARILY correspond to better preparation or “odds” for acceptance to a graduate school is not only statistically questionable, but shows a lack of the oft-touted “critical thinking” skills institutions like mine sell themselves as promoting and fostering.
Of course liberal arts colleges will dominate PhD PER CAPITA numbers when non-liberal arts institutions often offer vocational majors and have tens of thousands of students compared to a few thousand at most. Acceptance rates on average for liberal arts applicants vs. non-liberal arts applicants to graduate school at equally prestigious institutions (although finding ‘equally’ would be difficult) could be taken as indicator of quality of undergraduate preparation, but per capita rates alone are meaningless.
Articles like these, which I see floating around all of the time, only serve to make me shake my head in disappointment at the apparently well-educated individuals who are often so critical of other forms of education and who still misuse and misrepresent statistics. The education my college offers is terrific, and many students here who are seniors (including myself) have been accepted to doctoral programs already, but that does not equate to what you wrote."
and another:
"I’m a big fan of liberal arts colleges, but some caution needs to be taken in using “per capita Phd.” rankings. In short, per capita Phd production can be somewhat deceptive.
For instance, according to the American Institute of Physics, which has tracked graduation numbers in physics and phd origins since the 1930’s, notes that in 2010:
Lawrence college had 9 seniors majoring in physics in 2010
Beloit college had 8 seniors majoring in physics in 2010
A 25% rate of students going to get a phd when there are only 9 or so students, means that just 2 students go on to earn a Phd.
Meanwhile, UC Berkeley had 121 seniors majoring in physics, UC Santa Cruz had 114 physics majors, U of Illinois U-C, 103.
An 15% rate from a school with 121 or so students, means 18 students are going on to get doctorates — that means UC Berkeley is sending more than almost 10 TIMES as many students on to phd programs.
In fact, AIP research also has shown that in pure numbers, the LARGEST undergraduate source of phd recipients in phd came from research universities.
This doesn’t take away from the fact that students can – and do – get a very good undergraduate education in physics from small liberal arts colleges. But, it is incorrect to assume or imply that students attending research universities for physics are somehow all doomed to getting an inferior education in physics compared to someone who chooses a liberal arts college."
