In [[baseball]], '''wOBA''' ([[Help:IPA/English|/woʊ-bɑː/]], or '''weighted on-base average''') is a statistic, based on [[linear weights]],<ref>{{cite web|url=https://www.fangraphs.com/library/principles/linear-weights/|title=Linear Weights - FanGraphs Sabermetrics Library|website=www.fangraphs.com}}</ref> designed to measure a player's overall offensive contributions per plate appearance. It is formed from taking the observed run values of various offensive events, dividing by a player's plate appearances, and scaling the result to be on the same scale as [[on-base percentage]]. Unlike statistics like [[On-base plus slugging|OPS]], wOBA attempts to assign the proper value for each type of hitting event. It was created by [[Tom Tango]] and his coauthors for ''The Book: Playing the Percentages in Baseball.''<ref name="thebook">{{cite web|url=http://www.insidethebook.com/woba.shtml|title=wOBA - Weighted On Base Average|website=www.insidethebook.com}}</ref>
