Which of the following is not an Ivy League University?

The story behind the answer

Stanford is not an Ivy League university. The Ivy League is a specific athletic conference of eight private schools located in the Northeastern United States: Harvard, Yale, Princeton, Columbia, Brown, Dartmouth, Cornell, and the University of Pennsylvania. While Stanford is a top-ranked university, it’s on the West Coast and not part of that group.

Fun fact: "Ivy League" began as an athletics label in 1954, later becoming shorthand for academic prestige. Memory tip: the eight are H-Y-P plus Columbia, Brown, Dartmouth, Cornell, and Penn—all in the Northeast; Stanford is in California.
