Pizza! + Scatter Plots

As I research tasks and data sets for my students to analyze in our unit on bivariate data, I keep encountering unconventional scatter plots — scatter plots that are actually graphing more than two variables, or scatter plots really only graphing one variable and its frequency. I’ve loved giving these to my students to figure out and stretch their knowledge of how information can be presented.

One more: cost of a pizza compared to pizza size. Tons of great information here, but it doesn’t look like an 8.SP.1 scatter plot.
