Step 1
Count up the number of times the player has been at bat in the period you wish to measure. Most of the time, you want to measure every at-bat the player has had this season, but you can also calculate it by weekly appearances, monthly appearances, lifetime appearances and so forth.
-
Step 2
Take the total number of at-bats and subtract the number of walks, sacrifices and instances when the batter was hit by a pitch. (Those incidents do not count as at-bats when calculating batting average.) The result is the "official" number of at-bats for figuring batting average.
-
Step 3
Add up the number of hits the player has had over the period you wish to measure. This includes singles, doubles, triples and home runs. It does not include reaching base on an error or reaching base via a fielder's choice.
-
Step 4
Divide the number of hits by the number of at-bats and round off the result to the third digit after the decimal. That number is the player's batting average. To read a batting average, view the number as a percentage of 1.000. An average of .333, for example, means that the player hits the ball one time out of every three at-bats, while an average of .250 means that he hits the ball one time out of every four at-bats.
