This study investigates how closely key factors of team in the National Basketball Association (NBA) play up to their potential of winning game. Using the data mining techniques to obtain the correlations among game variables and build the rules of winning game, we provide prediction models of winning game for the 30 NBA teams in the duration of 1997-1998 to 2012-2013 seasons. The game score within 3 points will affect the precision of the prediction model based on the big data. The results after deleting data including the game score within 3 points indicate field goal percentage, 3 point field goal percentage, free throw attempts, turnovers, defensive rebounds, and steals are the key factors affecting the won-lost performance. It provides a better correct classification rate of 85% than the original data set. |
