| Four Factors Author: Dean Oliver | Four factors are box score derived metrics that correlate most closely with winning basketball games. These factors also identify a team’s strategic strengths and weaknesses. Four factors can be applied to both a team's offense and defense, hence it gives us eight factors.
Effective Field Goal Percentage=(Field Goals Made) + 0.5*3P Field Goals Made))/(Field Goal Attempts)
Turnover Rate=Turnovers/(Field Goal Attempts + 0.44*Free Throw Attempts + Turnovers)
Offensive Rebounding Percentage = (Offensive Rebounds)/[(Offensive Rebounds)+(Opponent's Defensive Rebounds)]
Free Throw Rate=(Free Throws Made)/(Field Goals Attempted) or Free Throws Attempted/Field Goals Attempted Comments: While these are the four essential factors that decide winning and losing in the NBA, the factors do not carry equal weight. 1. Shooting (40%) 2. Turnovers (25%) 3. Rebounding (20%) 4. Free Throws (15%) The number in parentheses is the approximate weight of each factor. Shooting is the most important factor, followed by turnovers, rebounding, and free throws. Each statistic measures a separate skill — there’s no reason that a team can’t shoot well, commit few turnovers, rebound a high percentage of its misses and make frequent trips to the free throw line. At the same time, a team can compensate for poor performance in one area by outstanding performance in another — hitting the offensive boards on a poor shooting night, for example. |
| Free Throw Conversion | The ability to get to the free throw line, and the ability to make free throws. Two metrics are used the measure free throw conversion.(Free Throws Attempted)/(Field Goal Attempts) explains how often a team shoots free throws |
