Though plus-minus has been an officially tracked statistic in the NHL since 1968, it remains a relative newcomer to the NBA, and is virtually nonexistent in college basketball. The plus-minus statistic, for those who are not already familiar with it, is designed to measure the scoring impact a player has on his team, even if that player is not the one doing the scoring. A player's plus-minus is calculated by adding the points his team scores while he is active on the court and subtracting the points the opposition scores while he is active on the court. In this manner, a player's plus-minus can reveal his contributions to team success that otherwise go unmeasured by standard statistics.
Using the play-by-play data provided by the NCAA for the 2009-2010 season, I've calculated the plus-minus for nearly every player that averaged more than four minutes per game. Each player's plus minus is his aggregate number for the entire season.
I've also calculated the offensive efficiency and defensive efficiency with respect to each player's active court time. Offensive efficiency measures the number of points a player's team scores per 100 possessions while that player is on the floor. Defensive efficiency measures the same for the opposition.
