# Basketball | A Guide to Stats

#### Offensive Stats

1. Games Played (GP)

Total number of games played for the season. These are only games listed as Game Film.

2. Field Goal Makes (FGM)

Total made shots other than free throws divided by games played.

3. Field Goal Attempts (FGA)

Total shots attempted other than free throws divided by games played .

4. Field Goal Percentage (FG%)

Total shots made other than free throws divided by field goal attempts.

5. 3-Point Field Goal Makes (3FGM)

Total 3-pointers made divided by games played.

6. 3-Point Field Goal Attempts (3FGA)

Total 3-pointers attempted divided by games played.

7. 3-Point Field Goal Percentage (3FG%)

Total 3-point shots made divided by 3-point field goal attempts.

Total free throws made divided by games played.

9. Free Throws Attempted (FTA)

Total free throws attempted divided by games played.

10. Free Throw Percentage (FT%)

Total free throws made divided by free throws attempted.

11. Effective Field Goal Percentage (eFG%)

The formula used is (2FGM + 1.5 * 3FGM) / FGA. This stat adjusts for the fact that a 3-point field goal is worth one more point than a 2-point field goal. For example, suppose Player A goes 4 for 10 with 2 threes, while Player B goes 5 for 10 with 0 threes. Each player would have 10 points from field goals, and thus would have the same effective field goal percentage (50%).

12. Points Per Possession (PPP)

Points per possession is calculated based off the following formula and is how we determine the number of possessions based on the data we have. The formula used is points scored divided by (FGA - OREB) + TO + (Y * FTA), where FGA = field goal attempts, OREB = offensive rebounds, TO = turnovers, Y = .44, and FTA = free throw attempts.

#### Defensive Stats

1. Rebounds (REB)

Total number of rebounds divided by games played.

2. Offensive Rebounds (OREB)

Total number of offensive rebounds divided by games played.

3. Offensive Rebound Percentage (OREB%)

Total number of offensive rebounds divided by total number of rebounds.

4. Defensive Rebounds (DREB)

Total number of defensive rebounds divided by games played.

5. Defensive Rebound Percentage (DREB%)

Total number of defensive rebounds divided by total number of rebounds.

6. Turnovers (TO)

Total number of turnovers divided by games played.

7. Assist to Turnover Ratio (A/TO

Number of assists divided by the number of turnovers.

8. Turnover Percentage (TO%)

The formula for both offensive and defensive turnover percentage is TO / (FGA + 0.44 * FTATO).

9. Steals (STL)

Total steals divided by games played.

10. Blocks (BLK)

Total blocks divided by games played.

11. Deflections (DFL)

Total deflections divided by games played.

12. Fouls (FOUL)

Total fouls divided by games played.

13. Charges Taken (CHG)

Total charges taken divided by games played.

14. Points For (PF)

Total points scored for your team divided by games played.

15. Points Against (PG)

Total points scored by opponents divided by games played.

1. Transition Points (TP)

Transition Points are calculated as any points scored within 8 seconds on the possession immediately following a Defensive Rebound or a Turnover by the other team.

2. Points Off Turnovers (PoT)

Points Off Turnovers are calculated as any points scored on the possession immediately following a turnover by the other team.

3. Second Chance Points (SCP)

Second Chance Points are calculated as any points scored on the same possession after an Offensive Rebound.

4. Points In The Paint (PiP)

Points In The Paint is calculated based off of shot location data. The value includes all made shots from inside the free-throw lane.

5. Value Point System (VPS)

The Value Point System is based on a formula that assesses player and team performance with a more well-rounded approach than other common forms of evaluation. The higher the number, the better. A VPS of 1 is about average. Formula:

Points + off. rebounds + def. rebounds + 2 * (assists + charges taken + steals + blocks)

divided by

FT misses + 2 * (FG misses + fouls + turnovers)

#### The Four Factors

How do basketball teams win games? While searching for an answer to that question, Dean Oliver identified what he called the Four Factors of Basketball Success:

1. Shooting (40%)

The shooting factor is measured using Effective Field Goal Percentage (eFG%). The formula used for eFG% is (FG + 0.5 * 3P) / FGA. This stat adjusts for the fact that a 3-point field goal is worth one more point than a 2-point field goal. For example, suppose Player A goes 4 for 10 with 2 threes, while Player B goes 5 for 10 with 0 threes. Each player would have 10 points from field goals, and thus would have the same effective field goal percentage (50%).

2. Turnovers (25%)

The turnover factor is measured using Turnover Percentage (TO%). The formula for both offense and defense is TO / (FGA + 0.44 * FTATO).

3. Rebounds (20%)

The rebounding factor is measured using Offensive Rebound Percentage (OREB%). The formula for this statistic is OREB / (OREB + Opp DREB).

4. Free Throws (15%)

The free throw factor is a measure of both how often a team gets to the line and how often they make them. The formula for both offense and defense is FTFGA.
