Features & Capabilities

The Galton Board App is an interactive probability demonstrator that visualizes the binomial distribution and the Central Limit Theorem through an on-screen Galton board. Beads roll and settle to illustrate how random events aggregate into predictable patterns, turning abstract statistics into a tangible experience.

Features include a Stock Market Data variant mapping historical monthly returns to bead paths, pause and slow-motion controls, and explanations of related concepts like IID, regression to the mean, law of large numbers, and the Gambler's Fallacy. Presented by Index Fund Advisors, this educational tool is ideal for students, educators, and finance enthusiasts.

This app simulates a Galton board, which is a pegboard that you drop marbles through and they bounce off the pegs and fall into bins. It shows a natural appearance of the famous Bell curve from statistics, and addresses a whole bunch of other math stuff like triangular numbers and Pascal’s triangle in a natural and interesting way. Beautifully done, could be a wonderful teacher’s aid or homeschool resource.

Love this product. The first time I saw a Galton Board was the the Science Museum in Flushing, NY. My mind was blown. I am so glad that a proper digital version was created. It would be awesome if Index Fund Advisors, Inc. could bring the physical product back.

This app was great for helping me understand the concept of bell curves for a class I’m taking this semester! I’m glad it’s out there for students like me :)
