Field goal percentage: Field goal percentage in basketball is the "ratio" of field goals "made" to field goals "attempted".  Its abbreviation is FG%.  Although three-point field goal percentage is often calculated separately, three-point field goals are included in the general field goal percentage.  Instead of using scales of 0 to 100%, the scale .000 to 1.000 is commonly used.  A higher field goal percentage denotes higher efficiency.  In basketball, a FG% of .500 (50%) or above is considered a good percentage, although this criterion does not apply equally to all positions.  Guards usually have lower FG% than forwards and centers. Field goal percentage does not completely tell the skill of a player, but a low field goal percentage can indicate a poor offensive player or a player who takes many difficult shots.  In the NBA, Center Shaquille O'Neal has a high career FG% (around .580) because he plays near the basket making many high percentage layups and slam dunks. Guard Allen Iverson often had a low FG% (around .420) because he took the bulk of his team's shot attempts, even with high difficulty shots.
