$SLG = (s + d + 2t + 3h)/(n_{AB}),$

where $n_{AB},$ is the number of at-bats for a given player, and $s, d, t, h,$ are the number of singles, doubles, triples, and home runs, respectively.

For example, in 1920, Babe Ruth was playing his first season for the Yankees. In 458 at-bats, he hit 73 singles, 36 doubles, 9 triples, and 54 home runs, which brings the total base count to (73 × 1) + (36 × 1) + (9 × 2) + (54 × 3) = 388. So his total number of bases divided by his total at-bats is .847, his SLG. The next year he slugged .846, and for 80 years those records went unbroken until 2001, when Barry Bonds hit 411 bases in 476 at-bats, bringing his SLG to .863, unmatched since.

It is often believed that a batter's Slugging Average is calculated as $SLG = (s + 2d + 3t + 4h)/(n_{AB}),$, where each base touched counts as one. This however, can be disproven by taking any Major League Baseball player's statistics, which can be found at MLB.com's Statistic's Website and calculating his sluuging percentage using both methods above. The number can then be compared to the SLG average listed on the MLB.com Statistic Website. Among other sites that accept this widely belived fallacy is Baseball Almanac's Statistical Formulas Website, listed here to demonstrate the method by which some incorrectly calculate Slugging Average.

 On-base plus slugging - Wikipedia, the free encyclopedia (547 words) On-base plus slugging, or OPS, is a baseball statistic which is calculated as the sum of a player's on-base percentage and slugging percentage. One fault of OPS is that it weights on-base average and slugging percentage equally, although on-base average correlates better with scoring runs. Discrepancies between published OPSes and the sum of on-base average and slugging percentage are due to rounding errors.
