Cartoon: The Mix-up

This cartoon was drawn in the style of Randall Munroe's xkcd web comic by Tubba Babar, a student from University of Toronto Mississauga and won second place in the cartoon category of the 2019 A-mu-sing Contest.  The cartoon can be used in discussing the difference between correlation and causation and the fact that observational relationships can often not distinguish between "A implies B" and "B implies A".  The graphic in the cartoon shows two things rising in prevalence over the same period of time. Thus, it can be used to discuss how many things have changed in the same direction over time, forming a vast number of spurious correlations.
