So I've been given the title "The correlation between changing managers and football results", and I'm struggling on how to structure the essay. After doing some research I've decided to talk about the "regression towards the mean" theorem but I don't think I'll be able to properly flesh out the essay simply by using that concept alone.
What other (potentially mathematically related) concepts and ideas could I talk about? (Bear in mind it's a 1000 word essay...)
Many thanks
