This is an example of a Quincunx, which we use in our series ‘How to teach the Normal Distribution’.
It will help students build up an intuitive understanding of what the shape of the Normal Distribution graph means. Before you start getting into the algebra.
We also think it’s remarkable because it shows how such a simple random process can be used to build this beautiful distribution.
