A vastly overrated baseball stat still in use because it's easy to calculate and still carries the mystique of being one third of the Triple Crown for hitters. To determine a player's batting average, divide the number of hits by the number of official at-bats. As noted above, sacrifice flies do not count as at-bats. Neither do sacrifice bunts, walks, or hit batsmen.

I say overrated because it doesn't accurately assess a hitter's ability to get on base, nor his ability to hit for power. The lesser known OPS, which stands for stands for on base percentage plus slugging percentage, measures a hitter's ability much more accurately.
