R is necessary for the remaining questions. The movie Moneyball is about how proper use of statistics in baseball
(called "sabermetrics") can bring unexpected success to a low-ranked, low-budget team. In it, the manager of the Oakland A's believes that (then) unpopular statistics, like a player's ability to get on base, can predict the team's ability to score runs better than traditional statistics, such as homerun counts and batting averages. By recruiting players who scored high in these underused statistics, he was able to improve the record of the team without needing to spend exorbitant amounts of money on the more mainstream players.
