How do you total hitting percentages in volleyball?

Question

kills v.s. attempts (.439)

Answer 1

Take the number of times the ball was killed and divide that by the number of times attempted to kill the ball

Example: 14 kills / 36 attempts = .388

Answer 2

Kills minus errors over attempts.

(Kills-Errors)/Attempts

Answer 3

Count your total kills, from that you minus your hitting errors and from that you divide by the amount of attempts.
