About this item
- 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

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.
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.
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.
Would absolutely recommend!
