Field hockey: Field hockey is a team sport of the hockey family.  The earliest origins of the game date back to the Middle Ages in England, Scotland, France and the Netherlands.  The game can be played on a grass field or a turf field as well as an indoor board surface.  Each team plays with eleven players, including the goalie.  Players use sticks made out of wood, carbon fibre, fibre glass or a combination of carbon fibre and fibre glass in different quantities (with the higher carbon fibre stick being more expensive and less likely to break) to hit a round, hard, plastic ball.  The length of the stick depends on the player's individual height.  Only one end of the stick is allowed to be used.  Goalies often have a different kind of stick, however they can also use an ordinary field hockey stick.  The specific goal-keeping sticks have another curve at the end of the stick, this is to give them more surface area to save the ball.  The uniform consists of shin guards, shoes, shorts, a mouth guard and a jersey.  Today, the game is played globally, with particular popularity throughout Western Europe, the Indian subcontinent, Southern Africa, Australia, New Zealand, Argentina, and parts of the United States (primarily New England and the Mid-Atlantic states).  The term "field hockey" is used primarily in Canada and the United States where ice hockey is more popular.  In Sweden the term "landhockey" is used and to some degree also in Norway.  It is a section of Norway's Bandy Association.  Until recently they called it "hockey", when it was changed to "landhockey".

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.
