Basketball statistics basics
Basketball is one of the most statistically analysed team sports. The core metrics: PPG (points per game), RPG (rebounds per game), and APG (assists per game) are the traditional triple-double stats. True Shooting Percentage (TS%) accounts for 2-pointers, 3-pointers, and free throws in a single efficiency metric. Player Efficiency Rating (PER) attempts to summarise all contributions into a single number normalised to 15 as league average.

What is a double-double and triple-double in basketball?
A double-double is when a player records double figures (10 or more) in two statistical categories in a single game — most commonly points and rebounds, or points and assists. A triple-double is double figures in three categories. Quadruple-doubles (four categories) are extremely rare in NBA history. Russell Westbrook holds the NBA record for career triple-doubles. For comparison, a 10-point, 10-rebound game from a centre is a double-double; a 10-point, 10-assist, 10-rebound game is a triple-double.
How is player efficiency rating (PER) calculated?
PER is a per-minute rating developed by John Hollinger that accounts for all positive contributions (points, rebounds, assists, steals, blocks) and negative contributions (turnovers, missed shots, personal fouls) per minute played, normalised so that the league average is always 15. A PER of 20+ indicates a very good player; 25+ is All-Star level; 30+ is historically elite (only a handful of seasons in NBA history). PER has limitations — it undervalues defence and efficient off-ball play.
What is the shot clock in basketball?
The shot clock requires the attacking team to attempt a shot that hits the rim within a set time: 24 seconds in the NBA and FIBA competition; 30 seconds in college basketball (NCAA). If the shot clock expires without a shot attempt hitting the rim, the ball is turned over to the opposing team. After an offensive rebound, the shot clock resets to 14 seconds (NBA/FIBA) rather than the full 24/30 seconds.
