<P> Henry Chadwick, an English statistician raised on cricket, was an influential figure in the early history of baseball . In the late 19th century he adapted the concept behind the cricket batting average to devise a similar statistic for baseball . Rather than simply copy cricket's formulation of runs scored divided by outs, he realized that hits divided by at bats would provide a better measure of individual batting ability . This is because while in cricket, scoring runs is almost entirely dependent on one's own batting skill, in baseball it is largely dependent on having other good hitters on one's team . Chadwick noted that hits are independent of teammates' skills, so used this as the basis for the baseball batting average . His reason for using at bats rather than outs is less obvious, but it leads to the intuitive idea of the batting average being a percentage reflecting how often a batter gets on base, whereas in contrary, hits divided by outs is not as simple to interpret in real terms . </P> <P> In modern times, a season batting average higher than . 300 is considered to be excellent, and an average higher than . 400 a nearly unachievable goal .

The modern - era record for highest batting average for a season is held by Napoleon Lajoie, who hit . 426 in 1901, the first year of play for the American League . The modern - era record for lowest batting average for a player that qualified for the batting title is held by Rob Deer, who hit . 179 in 1991 . While finishing six plate appearances short of qualifying for the batting title, Adam Dunn of the Chicago White Sox hit . 159 for the 2011 season, twenty points (and 11.2%) lower than the record . The highest batting average for a rookie was . 408 in 1911 by Shoeless Joe Jackson . </P> <P> For non-pitchers, a batting average below . 230 is often considered poor, and one below . 200 is usually unacceptable .
