Carlos Balsalobre points out this excellent "visualization" of the Gaussian distribution from the choice people make for their weights at the gym.
Here, you can see from the wear-and-tear that 60 lbs is the most likely choice of gym-goers, with the probability they want heavier or lighter weights spread out surprisingly symmetrically around 60 pounds, in what indeed looks like a roughly Gaussian distribution:
(Of course here we are just seeing a bundled version of people's weight preferences, you might really want a 64 pound weight, but you'd have to round down to 60 pounds).
It's also nice to see from the wear-and-tear that the manufacturer has designed a range that spans what different people seem to want.
However, if you had to choose 18 weights to make these gym-goer's happiest, you might do better by having more a few more choices in the middle range, and spacing out the far end choices a bit more.
Got several Mother’s day puzzle, couldn’t be happier but what’s the story with no pictures on the box?
