Supplies and Accessories
The Galton Board Desktop Probability Machine Brings to Life the Statistical Concept of Normal Distribution.
The Galton Board demonstrates centuries-old mathematical concepts in an innovative desktop device. It incorporates Sir Francis Galton’s (1822-1911) illustration of the binomial distribution, which for a large number of beads approximates the normal distribution. It also has a superimposed Pascal’s Triangle (Blaise Pascal, 1623-1662), which is a triangle of numbers that follows the rule of adding the two numbers above to get the number below. The number at each peg represents the number of different paths a bead could travel from the top peg to that peg. The Fibonacci numbers (Leonardo Fibonacci, 1175-1250), can also be found as the sums of specific diagonals in the triangle. The Galton Board is approved for STEM educational activities.
Design based on Sir Francis Galton's Galton Board Model
Built in Pascal's Triangle, Fibonacci Numbers and Standard Deviation Lines.
Rotates on its x-axis, causing 3000 beads to fall and form a bell curve.
