Calculate hitting percentage in volleyball by subtracting the total number of hitting errors from the total number of kills and dividing that by the total number of attack attempts. Hitting percentage is used to evaluate how effective a hitter is over a given span of games.

**Add up attack attempts and errors**Add up all of the attack attempts and hitting errors made by the player.

**Add up total attempts**Add up the total number of attempts made by a player over a given span of games. The sum of the total number of kills, errors and attempts equals the number of total attempts.

**Calculate the hitting percentage**Subtract the total number of hitting errors from the total number of kills, and divide the number by the total number of attack attempts to get the hitting percentage.
