Batting Average was among one of the first baseball statistics created. It is the quotient of hits over at bats.
It has been used as one of the pre-eminent batting statistics, as it is easily computed and has been in use for well over a century. It merely is the empirical probability of a player getting a hit in a given at bat. Batting Average is an official statistic. Currently, players qualify for the league batting average championship based on rule 10.22(a) of the 2009 Official Rules http://mlb.mlb.com/mlb/downloads/y2008/official_rules/10_the_official_scorer.pdf, retrieved on 2009-10-21.. Batting averages are traditionally expressed rounded to three decimal places.
