Fifty years ago, the 1975 Cincinnati Reds won the World Series. The statistics available then for fans were basic but understood. Fifty years later, there is a blizzard of new statistics, and the way the game has been played and understood has radically changed. Many of those changes came about due to outsiders discovering new ways to analyze baseball data and teams adopting their findings. This course will trace the history of baseball analytics, explain the new statistics and acronyms, and discuss the influence of the revolution on the game.
