| '''Gross Production Average''' or '''GPA''' is a [[baseball statistic]] created in 2003 by [[Aaron Gleeman]],<ref>http://aarongleeman.com/2003_11_23_baseballblog_archive.html</ref> as a refinement of [[On-base plus slugging|On-Base Plus Slugging]] (OPS).<ref>http://www.hardballtimes.com/main/article/about-those-stats/</ref><ref>http://www.aarongleeman.com/2003_11_23_baseballblog_archive.html</ref> GPA attempts to solve two frequently cited problems with OPS. First, OPS gives equal weight to its two components, [[On Base Percentage]] (OBP) and [[Slugging Percentage]] (SLG). In fact, OBP contributes significantly more to scoring runs than SLG does. [[Sabermetrician]]s have calculated that OBP is about 80% more valuable than SLG.<ref>http://www.hardballtimes.com/main/statpages/glossary/#gpa</ref><ref>http://www.hardballtimes.com/main/article/about-those-stats</ref> A second problem with OPS is that it generates numbers on a scale unfamiliar to most baseball fans. For all the problems with a traditional stat like [[batting average]] (AVG), baseball fans immediately know that a player batting .365 is significantly better than average, while a player batting .167 is significantly below average. But many fans don't immediately know how good a player with a 1.013 OPS is. | | The writer's name is Andera and she believes it seems fairly good.

| The basic formula for GPA is:<ref>http://www.hardballtimes.com/main/statpages/glossary/#gpa</ref> <math>\frac{{(1.8)OBP} + SLG}{4}</math>
| |
| | |
| Unlike OPS, this formula both gives proper relative weight to its two component statistics and generates a number that falls on a scale similar to the familiar batting average scale.<ref>http://www.nytimes.com/2007/02/25/sports/baseball/25score.html</ref>
