Who’s #1 — Mathematics of Ranking mini-course

single session
(of an eight-session minicourse)

Sunday, January 22 at 7:00 pm ET (New York)


What’s your favorite?  Who's number 1?  Who was the greatest ever?  Each of these questions involves ranking.  Ranking has many applications from determining top colleges to choosing playoff teams.  In this program hosted by Tim Chartier, MoMath’s 2022–2023 Distinguished Visiting Professor for the Public Dissemination of Mathematics, we will learn several ranking systems including PageRank, Elo ranking system, the Colley method and the Massey method.  PageRank was developed by Google for their search engine results.  Elo began as a method to rank chess and is used in many applications like online gaming.  The Colley and Massey methods are used extensively in sports ranking applications.  Over the course of several Sundays, we will learn these methods, how to code them, and how to adapt datasets so items can be ranked.

Tim Chartier is an applied mathematician, popular author, and professionally-trained mime from Davidson College who brings to MoMath his expertise in data analysis, computer science, sports analytics — and the performing arts!
