Total average is a baseball statistic devised by sportswriter Thomas Boswell in the 1970s. The statistic is designed to measure a hitter's overall offensive contributions. The definition of the statistic is simple. A player gets a credit for every base he accumulates and a penalty for every out he makes. So a player gets one credit for a single, walk, stolen base or being hit by a pitch; two for a double; three for a triple; and four for a home run. A player's Total Average is calculated by adding all the bases together and dividing them by the number of outs the player makes. The formula is: where *TA = Total average *TB = Total bases *HBP = Hit by pitch *BB = Walks *SB = Stolen base *CS = Caught stealing *AB = At bats *H = Hits *GIDP = grounded into double play Because Total average emphasizes walks and extra base hits - and de-emphasizes singles - it has much in common with statistics developed by Bill James and other sabermetricians. Like OPS, total average gives credit to players who draw a lot of walks and hit with a lot of power: Babe Ruth, Barry Bonds, Ted Williams and Frank Thomas for instance. James himself was critical of total average. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Total average」の詳細全文を読む スポンサード リンク
