WOBA is an advanced baseball statistic that stands for Weighted On-Base Average. Unlike traditional stats such as batting average, WOBA takes into account a player’s overall ability to get on base, including walks and extra-base hits. It is calculated by assigning weights to each type of plate appearance (such as singles, doubles, and home runs) based on how valuable they are in producing runs, and then dividing the sum of those values by the total number of plate appearances. WOBA is considered a more accurate indicator of offensive production than traditional statistics, and is used by many advanced baseball analysts and teams.
