This made me laugh today. I was using the normal distribution curve to explain Six Sigma and had asked the audience to consider the heights of doors, people, feet sizes ... And had put a sketch of the normal distribution curve on a flip chart. I overlayed the curve with three sigma.

Hameed bemoaned the idea that his feet were beyond the line to the left of the graph: much merriment ensued!

I had to agree and said that my size 47 feet were off to the right as I find it very difficult to find them. DW
