Formula. The batting average is calculated in the following way: Batting Average = Total number of hits / Total number of at bats. For example, if a player has 200 at-bats, and has 70 hits, then his Batting Average is 70 / 200 = 0.350.
A good average would be .300 - .330 with a superior average being above that. and a crappy one would be below .250. If you want to figure a batting average you take the number of hits divided by the number of at-bats so if you have 35 hits and 122 at-bat your average would be .286.
