r/faux_pseudo's "Distribution of particles by size from a Cracker Jack box

I love my fellow Reddit data geeks over at r/dataisbeautiful. Redditor faux_pseudo created a frequency chart of the deliciousness found in a box of Cracker Jacks.

I think it would be funny to ask students to discuss why this graph is misleading (since the units are of different size and the pop corn is divided into three columns). You could also discuss why a relative frequency chart might provide a better description. Finally, you could also replicate this in class with Cracker Jacks (one box is an insufficient n-size, after all) or try it using individual servings of Trail Mix or Chex Mix or order to recreate this with a smaller, more manageable sample size.

Also, as always, Reddit delivers in the Comments section:
