Although batting average doesn't tell the whole impact of a softball player, it is still one of the most important statistics in the game. Dividing the number of hits by the number of times atbat calculates this seeming simple metric. However, what constitutes a hit or an atbat isn't as obvious as it initially appears. In general terms, it's a hit only when a batter gets on base by her own merits. These rules and the batting average calculation also apply to baseball.

Count the number of atbats for the player, minus the times she is walked, hit by a pitch, sacrifices or reaches base by a catcher's interference. For example, if a player goes up to bat 20 times, but is walked three times and sacrifices twice, she has 15 official atbats.

Count the number of singles, doubles, triples or home runs for the player. Only these base hits will figure into a batting average.

Divide the number of hits by the number of atbats. Round the number to the third digit after the decimal. For example, if the player had eight hits in 15 atbats, divide eight by 15 to get 0.533333. Rounding this number and removing the preceding zero gives you a .533 batting average.
