## Baseball Statistics

Team sports are fun and exciting for many children.  However, they can also be used to review math concepts that children tend to struggle with.  Our last post in this series talked about how soccer statistics use math.  Baseball is another sport filled with statistics.  Children who play baseball will enjoy coming home and finding out for themselves their own baseball statistics and maybe even the stats of their team.

## Batting Average

One of the most talked about baseball statistics is a player’s batting average.  This number tells watchers how many times a player gets a hit compared to the amount of times he gets up to bat.  Simple division is used to figure out a batting average.  For each game divide the number of hits the child gets by the number of times he is at bat.  The answer should result in a decimal answer.  (For example:  A child gets up to bat 8 times, but he only hits 5 times.  The equation would be 5 divided by 8 giving a batting average of 0.625.)

## Fielding Percentage

This baseball statistics attempts to measure how well a player does in the outfield.  It uses both how many chances a player had to make play and how many errors were made with those chances.

• Take the number of chances the outfielder had and subtract the number of errors made.  (A child who had 15 chances to make plays and made 3 errors would subtract 15 – 3 to get 12.)
• Divide that number by the total number of chances. (In this example, 12 would be divided by 15 which gives you 0.8.)
• Move the decimal in the answer two places to the right to end up with a percentage.  (0.8 becomes 80.%)

## Walks and Hits Per Inning

Pitchers can keep track of their own baseball statistics as well.  This statistics helps a pitcher see how many times they would have allowed a batter to reach base (ignoring the actions of the outfielders).  Simply keep track of all the walks and hits a pitcher allows during the entire game.  (This would be simple to do using tally marks on a piece of paper.)  After the game, divide the total number of walk and hits allowed by 9 (or the number of innings if the game goes into overtime).  The answer gives you the average number of walks and hits allowed per inning.  For example a child pitches a total of 113 walks and hits during a game.  Divide 113 by 9 to get 12.556.  Because you are dividing by 9, many of the answers will be repeating decimals giving your child a great opportunity to practice rounding back in the answer.

Baseball is a fun sport, but it is also a great way to practice some common math skills.  Use your child’s baseball statistics to practice math in real life situations.  In our next post, we will deal with common basketball statistics.
