Shapley-shubik power distribution.

The Shapley–Shubik power index was formulated by Lloyd Shapley and Martin Shubik in 1954 to measure the powers of players in a voting game. The index often reveals surprising power distribution that is not obvious on the surface.

FAPPlet. Shapley-Shubik Index. The Shapley-Shubik index is a measure of a voter's power in a weighted voting system. To calculate the index of a voter we first list all of the permutations of voters. If there are 3 voters there will be 3! = 6 permutations, with 4 voters there will be 4! = 24 permutations, and so forth.This Demonstration lets you compare the proportion of votes a player has versus that player's power as measured by the Shapley–Shubik and Banzhaf power indices.
