Finding the Best Dog Treat with Statistics

A dog owner used the Bradley-Terry statistical model—a method for ranking competitors based on pairwise comparisons—to determine his Greyhound's favorite treat by conducting daily preference tests. The model assigns strength scores to each treat based on head-to-head matchups, similar to the Elo rating system used in chess. The experiment involved presenting two different treats daily and recording which one the dog chose to identify an overall ranking.
