With another round of elections coming up, the Electoral Vote Predictor can be used in a number of ways. The site tracks state-by-state polls for President and Senators, and presents the results in map, spreadsheet, table, and graph form. It also has a lively bog that tracks current election news, with a special emphases on polling and statistics.
This resource can be used in a number of areas, including science, math and social studies. It provides a graphic example of how the Electoral College works, and shows that while a single observation may be inaccurate, a large observation set will usually be very close to the final result.
The site is maintained by Andrew S. Tanenbaum, a U.S. citizen and professor of Computer Science living in Amsterdam, and Christopher Bates, teaching at UCLA and Cal Poly Pomona.
Highly recommended.
