Discriminative Power of Basketball Game-Related Statistics by Level of Competition and Sex

Abstract

The purpose of this study was to identify the basketball game-related statistics that best discriminate performances by sex of players and level of competition. Archival data were obtained from the International Basketball Federation boxscores for all games during men's senior (n=62), men's junior (n=64), women's senior (n=62), and women's junior (n=42) World Championships. The game-related statistics gathered included 2- and 3-point field-goals (both successful and unsuccessful), free-throws (both successful and unsuccessful), defensive and offensive rebounds, blocks, assists, fouls, steals and turnovers. For the analysis only the close games were selected (N= 105, 1 to 12 points difference). Men's teams were discriminated from women's teams by their higher percentage of blocks and lower percentage of steals and unsuccessful 2-point field goals. Junior teams were discriminated from senior teams by their lower percentage of assists and higher percentage of turnovers. In the two-factor interaction, the teams were mainly discriminated by the game-related statistics identified for level of competition.
