Is it possible to forecast if a team will win a game in a simple and precise manner? In a game, which team statistics are most important? The so-called Four Factors of Basketball is a phrase that was coined less than two decades ago to explain previously unanswered questions.
This study examines some of the most important aspects that influence a basketball game. The essential goal is to figure out what they are and how they can be used. The author analyses an idea that has gained popularity in recent years in the first part. An estimated number of victories is determined using a projection model based on those criteria. The reader will be informed about the significance and correctness of the results and the necessary analysis, it is hoped.
One of the most difficult difficulties in basketball, and not just, is providing accurate team win forecast reports. Every year, coaching staff and analysts, data scientists, and other stakeholders with relevant technical backgrounds pool their talents. Their objective is to figure out which individual or team numbers matter the most and in what way. After decades of data collecting and processing, it is now able to highlight the various areas of attention and construct effective projection models based on them.

Methodology and Data Collection
All 30 NBA clubs’ data was collected and used for this study, which spanned the seasons 2012/13 through 2016/17. There were eight categories considered, which may be divided into offensive and defensive metrics. Only the regular season was looked at.
The outcome, which was the expected record for each team from 2012 to 2017, was calculated using three mathematical equations based on two separate models (150 observations in total). The second one was analyzed using the linear least squares regression approach. After then, the numbers were compared to the actual number of wins.
Four Factors Explained
In the NBA, hours of research have gone into determining what the most important aspects are in winning a game. Dean Oliver, a data analyst, and basketball coach, came up with a notion that was going to transform the way people think about statistics and basketball. Those features, according to his “Four Factors” thesis, are predicated on how a possession could end. Teams may win by being efficient in shooting, turnovers, rebounding, and free throws. They are assessed using four-team stats, each of which is given a distinct weight. Oliver defined Effective Field Goal Percentage or EFG% (40 percent), Turnover Rate or TOV% (25 percent), Offensive Rebound Rate or ORB% (20 percent), and Free Throw Rate or FTR% (15 percent).
Because it takes into consideration the fundamental principles of basketball, this hypothesis appears to be fairly accurate. Score frequently, avoid turnovers, grab every rebound, and get shooting fouls.
- Effective Field Goal Percentage is a replacement for FG Percentage, which rises when a team makes three-pointers.
- A team’s turnover rate is calculated as the number of turnovers committed per 100 possessions.
- The proportion of disputed rebounds a team captures after its own missed attempts is known as the offensive rebound rate.
- The number of free-throw attempts per field goal attempt is known as the free throw rate. Free throws contribute to the opponent’s foul problems in addition to providing easy scoring.
Their use has grown in prominence to the point that they are now being shown on television networks. Trevor Fleck, who produced telecasts for the Minnesota Timberwolves, employed the four components in his halftime performance, for example.
