Description
Product details:
NameGalton Board, effective demonstration statistics laws
Material: acrylic plastic.
Color: Yellow, White, Red
Size: 40.5 x 30.5 x 3.5 cm.
Application:
Turn the device upside down, pour all the balls into the V insert and turn it over so that V is on the upper part of the device. Pull the insert to drop the balls, collisions with peg arrays are randomly distributed, the stakes are equidistant to the left and right of each other, and each horizontal position is exactly in the middle of the two pegs when balls come into contact with peg arrays. 1/2 per probability that they will fall left or right and then hit the next layer of pegs etc. until they fall into narrow slots in the ground giving a number ball of the same size falling from the entrance. As long as number balls are quite large, stack up at the bottom in a pattern that is approximately equivalent to a normal density function (i.e. high in the middle, low at the ends and low in the middle). An old bell pattern with left-right symmetry, where N is number layers nails.
