About Galton Board App
The Galton Board was invented by Sir Francis Galton in 1873 to illustrate the binomial distribution. Through our app, we've recreated this educational tool to demonstrate how, with a large number of beads and rows of hexagons, it approximates the normal distribution - a concept known as the Central Limit Theorem.
Key Features:
• An interactive Galton Board that displays the principles of probabilities and the binomial distribution.
• Detailed explanations of related mathematical concepts, including probability theories, independent identically distributed (IID) random variables, regression to the mean, the law of large numbers, the random walk, the Gambler's Fallacy, and more.
• A "Stock Market Data" version, simulating the probabilities of a range of historical monthly market returns, and demonstrating their correlation with the binomial distribution.
• The 'Historical Monthly Return Beads' featured with the Stock Market Data, where beads fall through the board based on monthly historical returns for a choice of 20 index portfolios.
• Pause or slow-motion options to study the bead movement and distribution patterns in detail.
The Galton Board App is ideal for statistics, math, and stock market enthusiasts. It is not just an app, it's an immersive, hands-on approach to understanding probabilities, the binomial distribution, and the stock market behavior. Presented by Index Fund Advisors, this app is your go-to educational tool. Download now and embark on a fascinating journey into the world of probabilities and the "law of unreason" as referred to by Sir Francis Galton himself!

Beautiful representation of some of the most fascinating real world math
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.

Great product for stats student and fans
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.
