Price History of Galton Board

Description of Galton Board

Originally conceived in 1894 by Galton, the board consists of countless balls traversing down through a maze of pins. At every pin, they have a single choice: go left or right. Although the possibilities seem limitless, a pattern soon emerges. But how does this really work? This app is a simulation of the famous Galton board and is intended for educational purposes. You can adjust the board size, and send over a thousand balls bouncing down the board. On iPad you can even run multiple simulations simultaneously with multiple windows. The results are visualized by a bar chart. The Galton Board is closely related to Pascal's Triangle, Newton's binomium and probability theory in general. For experiment fidelity and performance, the balls do not collide with each other. I hope this app helps people grasp chance at least a little bit better. Love the app, or have improvements/suggestions? Let me know!

Reviews of Galton Board

  • Excellent Galton Board App

    This app is fun to use because you can vary the number of rows and the number of beads. I especially like seeing the exact number of beads in each bin so I can look at the statistical variation from cycle to cycle. I would like to see a repeat button added so I would not have to reenter the number of beads every time. Having a 1000 bead button would also be convenient for running a many bead simulation. The app seems to produce the Pascal’s triangle bead bin probabilities very well. The random number generator appears to have a random offset so each run of the app produces different results. Would you comment on the random number generator you use? Great app! Thank you!
  • Please fix the math! It’s misprogrammed but love the idea!

    I want to give this app five stars, but after 20 trials, it’s incredibly clear that it has been misprogrammed. for example, you will always see a higher number than expected of balls on the outside, which should average out to 1/8, 1/16, 1/32, 1/64 depending on how many rows.

    Developer Response

    Hi Dan, thank you for bringing this to my attention. I was able to reproduce the issue, and it has been resolved in the latest release. - Edwin
  • Very nice

    Good representation of the theory.
