Baseball Stats

Introduction

If you ever watched a baseball game, even once, you have heard the terms batting average and earned run average. These are probably the best known statistics used in baseball, but there are many others. Statistics are used by professional baseball teams to prepare for games by developing a plan for both pitching to and hitting against their opponents. Managers also use statistics about their own players during a game to decide such things as the order of the lineup, which pinch hitters to use, or which relief pitcher to bring in. In this lesson, you will take a closer look at baseball statistics to try to develop a better understanding of how they are used and analyzed.


Exploration

In baseball, a no-hitter is a game in which a pitcher, or pitchers, gives up no hits while pitching at least nine innings. A pitcher may give up a run or runs so long as he pitches nine innings or more and does not give up a hit. A perfect game, on the other hand, is one in which no hitter on the opposing team has reached first base in nine innings of play.

Go to MLB No-Hitters. Use the data from 1970 to the present to answer these questions:

  • What is the average score of the no-hitters pitched since 1970?
  • Which scores appear most often in the data?
  • What is the mean, median, and mode?
  • Which year had most no hitters?
  • Which league has had most no hitters?
  • What is the ratio of perfect games to no-hitters?

In this part of the lesson, you will use data found in Stats on the MiLB.com site to solve problems based on statistical information about Minor League baseball teams. You will work with a group on one of the questions below, assigned by your teacher, as instructed on the Baseball Statistics student sheet.

  • Which Pacific Coast League team had the best batting average in 1998?
  • Which Pacific Coast League team had the best batting average in 1997?
  • Which Pacific Coast League team had the best batting average in 1996?
  • Which International League team had the best batting average in 1998?
  • Which International League team had the best batting average in 1997?
  • Which International League team had the best batting average in 1996?
  • Which American Association League team had the best batting average in 1997?
  • Which American Association League team had the best batting average in 1996?

Go back to the Stats site. This time, instead of answering a question given to you by your teacher, work with your group to select data from the website and then think up three questions that can be answered using data from the archives. Write each question on an index card and then write the solution on a separate card.
