A shot on goal is a scoring attempt. A count of how many shots are taken by a team is kept and this is often used as rough guide to which team is being more aggressive and dominant. A scoring attempt in hockey (as opposed to soccer) is officially counted as a shot only when it is directed on goal, resulting in a goal or requiring the goaltender to make a save. The numbers of shots and saves in a game are especially relevant to goaltenders, whose save percentage is based on how many shots did not get past them. The number of shots taken by skaters and the percentage on which they score is also measured, but these numbers are generally given less weight. Some shots on goal are considered more likely to result in a goal and are called scoring chances.
