Cartoon: Consensus New Year

A cartoon with an unusual graph suitable for use in teaching about cumulative distribution functions – topics for discussion include how a cdf looks like a step function for a discrete variable and a continuously increasing function over the range of a continuous variable (ask the class if the cartoon gets this correct or not). The cartoon is number 2092 (December, 2018) from the webcomic series at xkcd.com created by Randall Munroe.
