On Colleges Losing Their Minds (or Other Tales of Small N Inferences)
According to the U.S. Department of Education, National Center for Education Statistics there were 7,236 Postsecondary Title IV institutions in the US as of 2013 (two- and four-year institutions). That translates into thousands upon thousands of classes on a given day.
Hence, it makes perfect sense to draw grand conclusions about higher education in America from a handful of cases.
By the way: many of those thousands of courses taught each day are basic stats classes. You know, if anyone is interested.
