But what makes these numbers so powerful? Sports statistics use descriptive statistics to summarize massive amounts of performance data into single, meaningful numbers that teams, coaches, and fans can use to make decisions worth millions of dollars. Let's explore how the math you're learning in statistics class is the same math used to evaluate professional athletes! One of the most famous statistics in sports is the batting average in baseball. It answers a simple question: "What proportion of the time does this player get a hit?" A .300 average means the player gets a hit 30% of the time - that's considered excellent! The batting average is actually a proportion - a type of mean that tells us the average success rate. Question: If Player A has 50 hits in 200 at-bats, and Player B has 25 hits in 100 at-bats, which player has a better batting average?
