What value is cross country GDP correlation? [Part One]
Cross-country GDP correlation from 1991-2009 The above graph borders on chartjunk (and is nothing like Paul Butler’s amazing Facebook map).

R at Wikimedia
Last year Wikipedia rolled out a pilot program to use Wikipedia article creation as an assignment in the classroom. Students wrote articles on a topic area and rather than turning them into a professor and forgetting about it they upload it to Wikipedia and expose it to readers around the world. 24 schools inside the United States–including N...
