Volleyball Attack Efficiency

Attack efficiency is the single most important hitting statistic in volleyball, balancing kills against errors and total swings.

Formula

Efficiency = (Kills - Errors) / Total Attempts

The result ranges from -1.000 (all errors) to 1.000 (all kills). Zero means kills equal errors. In college and professional volleyball, an efficiency above .300 is excellent and above .400 is elite.

Esempio Risolto

A hitter records 15 kills, 4 errors, on 35 attempts.

  1. Efficiency = (15 - 4) / 35 = 11 / 35 = 0.314
  2. Kill percentage = 15 / 35 x 100 = 42.9%
  3. Error percentage = 4 / 35 x 100 = 11.4%
