Abstract

Sports teams, schools, hospitals, universities, films, online gamers: they all get ranked into league tables. But do these rankings mean anything? Does being top of the league really equate to being the best? This lecture considers how the play of chance can influence rankings, and how we can use the theory of probability (and some computing power) to see whether the cup-winning team was just lucky. In passing, we shall explain the curse of ‘Hello’ magazine, as well as why tall people tend to have shorter children. Using local data on MRSA rates in hospitals, SAT scores in primary schools, teenage pregnancy in local authorities and so on, we will see why league tables are often not to be trusted.

Audience: General public, ages 16+
