Imagine that I want to rank the top 3 foods of all time. I want to ask ten different people to answer this question. So I get answers such as: Mashed Potatoes > Artichokes > Carrots Beef Jerky > Mashed Potatoes > French Fries ...etc. Is there an established method or algorithm for compiling these rankings together? It's clear that you can't simply ask everyone for their 'one favorite', because if everyone says Beets, the results say nothing about the second best food. This sort of thing has a lot of applications in sports statistics, ranking teams, players, etc.
