Galton Board

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!

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.

Good representation of the theory.
