At the Albert Heijn, You Get About 2% More Potatoes Than What it Says on the Label - JASP Services BV
A week ago I started a small quality control project where I measured twenty “1 kg” Albert Heijn (AH) potato bags in order to assess whether or not AH is systematically underfilling them, as some soci...

This week's blog post features "raincloud plots", a relatively recent development in data visualization.

Will the raincloud plot gradually replace the box plot? It just might!

If you cannot sleep because you keep wondering why the two whiskers of a box plot can be of very different length (and why this is a Very Sensible Idea), then this blog post is for you! :-)
