The galton board (named after and invented by Sir Francis Galton) is a physical device consisting of a vertical board with rows of interleaved pegs. The board illustrates the central limit theorem, by showing that beads dropped onto the pegs in the middle at the top end up in bins at the bottom approximately following a normal distribution, with most beads staying close to the middle.
