Galton Board

4.7 4.7 out of 5 stars 804 ratings
  • The Galton Board is a desktop probability machine which brings to life the statistical concept of normal distribution; As you rotate the Galton Board on its axis, you set into motion a flow of steel beads that bounce with equal probability to the left or right through several rows of pegs
  • As the beads accumulate in the bins, they approximate the bell curve, as shown by the yellow line on the front of the Galton board;This hands-on Galton Board allows you to visualise the order embedded in the chaos of randomness
  • Measuring 7.5 inch by 4.5 inch, this desktop probability machine is the perfect gift for physics lovers or just as a uniquer desktop toy
  • IMPORTANT: Due to an anti-static additive, the opacity of the board may on rare occasions vary slightly

Clever and educational
I do like this. Very visual method of teaching fundamentals of randomness to kids. It comes with one 'oversize' bead to demonstrate even more randomness but in my case the bead was too large to go through the gaps and got stuck. Other than that I highly recommend it. I also recommend that the manufacture emove the 'outlaw' bead because: 1) it's hard to see until it gets stuck 2) does not really add to the learning experience and 3) causes non-proportional ill will and negative reviews with customers and thus a reduction in sales. That's not good.

5.0 out of 5 stars Nice "toy"
Reviewed in the United States on October 24, 2019

Galton board - why does one need it? Well, it's a very nice "toy" with a mathematical background: the very interesting Gaussian curve of the normal distribution,. Having said that ... I have to admit, that it might be rather a present for someone who's keen on maths. I do like maths (always did) and for me the Galton board is something like the Newton's Cradle: Having put it on my desk, I do flip it from time to time ... ;-)

Maybe a little warning: There is an "Import Fees Deposit", which cost in this case additional 10 bucks. I live in Austria - therefore I had to pay about 55 bucks for my Galton Board - that includes all of the fees. Since Amazon did state it in the ordering process, I did know everything beforehand. No problem around here.

This item was exactly what I expected - the base is a bit light but it still stands with no issues and is great to watch it sort out the balls. All balls are the same - some boards have a single ball that's a different color to show the randomness of any one ball, but this one are all the same color. Regardless, it's a great item and would make an excellent gift for any stats or math nerd in your life. Even the people I work with who aren't as obsessed with data as I am still think it's really cool and love flipping it to watch the balls fall into the normal distribution.

Would absolutely recommend!

5.0 out of 5 stars Very Impressed With This Desktop "Math in Motion" Galton Board
Reviewed in the United States on July 12, 2019

I purchased my Four Pines Publishing Galton Board (GB) from Amazon about three weeks
ago. It arrived in perfect condition. I am not a professional statistician; however, I have been
involved in Monte Carlo code development and applications for many years, so I appreciate
a good normal distribution. This GB provides a repeatable dynamic demonstration of how a
normal distribution of many beads is produced by the random behavior of each bead, one
at a time. "Order in apparent chaos" as written by Sir Francis Galton (1889).

When I opened the shipping package, I found that the GB box itself is loaded with
useful information printed on the outside about Sir Francis Galton, the Pascal triangle,
Fibonacci numbers, and the Golden Ratio. Inside the box is a very nice 6 page pamphlet
with additional information about the normal distribution, its standard deviation,
the Central Limit Theorem (and regression to the mean), and facts about this GB: 3000
(steel) beads, 12 rows of pegs (in a quincunx geometric pattern), and 28 bead bins.

This GB device itself is a good size for a desk (7.25x4.5x2.56 inches), is made of sturdy plastic,
and is trivial to operate. It is very evident that significant effort was spent on the design
and engineering of this GB. The rotating GB is made of clear plastic for easy viewing
of the bead flow. This GB can be moved with one finger without knocking the device over.
The beads bounce off of each peg randomly without ever getting stuck and always end up
in one of the bead bins at the bottom creating the normal distribution of beads. Each GB
board tilt cycle works without any bead flow problems in either direction. Although the GB
is sturdy, it is not meant for rough treatment.

The front face of the GB contains important information. The normal distribution curve is
drawn on the face for easy comparison to the observed bead distribution. The 1, 2, and 3
sigma (standard deviation of the distribution of beads) lines are also drawn. The 2 sigma
line is slightly misplaced, but that does not detract from the usefulness of the overall
presentation. The Pascal triangle with the symmetric numbers of paths to get to each bead
bin is also shown. The triangle apex is directly under the bead reservoir opening for bead
flow visualization through the triangle. The rotating GB itself has very nearly the dimensions
of a Golden Rectangle. The bottom of this GB base shows where to find many informative
GB videos and mathematical facts, along with STEM (Science, Technology, Engineering, and
Math) worksheets for students in grades 5th through 12th.

This GB even has an Easter Egg: one brass bead that is a slightly different color from the
steel beads. The brass bead is hard to find, but it is there (my wife found it first). It is
interesting to see where the brass bead ends up after each GB cycle. The brass bead is
unlikely to land in the same bead bin in successive GB cycles.

My bottom line is that I am really enjoying this "Math in Motion" desktop statistical gadget.
It is definitely a unique conversation piece. The GB is also a fun educational device that could
spark interest in a STEM career for an undecided student. I highly recommend this GB to
anyone with an interest in observing, learning about, and/or teaching the statistical behavior
of many natural and other random phenomena.

4.0 out of 5 stars The desk toy for statistics nerds
Reviewed in the United States on October 26, 2022

As a big probability/statistics enthusiast, I love the Galton Board. It's a perfect visualization of the gaussian curve and a fun way to explain distributions to people. It's got lots of distinct visual features that illustrate other principles, especially for sigma/deviation and confidence intervals. Basically it's a desk widget and a teaching tool.

That said, it's still very pricey for what you get. It's sturdy and packed very well, but fairly small and packed in with several haphazard flyers explaining the symbols and equations in messy small text. For this price, it would benefit from a clean single card or booklet to accompany it.

Aside from that pickiness, I really love it. As a desktop ornament, it gets a lot of attention, questions, and is regularly "re-rolled" by passerby like a fortune wheel. It would be great to have simpler, handier text to keep alongside it.

This really will teach you about probability distribution.

You can also tell how "level" the toy is by how the balls fall in the curve. This is an example of a "Skew" that you might find in a survey. I really enjoy comparing a super level surface to one that is a little off.

It also has a nice card that shows some other things you can learn from the toy.

It also gets you some nerd street cred which -- you know -- who doesn't want that!!

5.0 out of 5 stars Simple, fun demonstration of Normal Curves
Reviewed in the United States on April 10, 2021

I'm a high school math teacher, and this board is a fun addition to lessons on the normal distribution. It then just sits on my desk top, and students often get curious about it and start playing with it and asking questions about it. There is one small brass ball included to demonstrate what happens to individual outcomes when normal distributions are created. It can be hard to find but that's part of the fun, too.
