This study aims to depict two-point and three-point shooting trends and explore their influence on game outcomes in the NBA across 40 consecutive seasons. Therefore, the following game-related statistics were considered: total points per game (PPG), games played (GP), field goals made (FGM), field goal attempts (FGA), field goal percentage (FG%), two-point field goals made (2PM), two-point field goal attempts (2PA), two-point field goal percentage (2P%), three-point field goals made (3PM), three-point field goal attempts (3PA), three-point field goal percentage (3P%), and a three-point field goal to two-point field goal ratio (3P/2P). The fixed-base indexes and inter-decade ANOVAs or Friedman tests were used as the main statistical tools. The number of 3PA significantly increased over time, while the number of 2PA decreased. A significant increase in 3P% was also observed, whereas 2P% remained relatively stable over the analyzed period. This study also revealed a higher number of ball possessions and more points scored per game, especially in the last decade of NBA competition.
本研究旨在描绘 NBA 连续 40 个赛季的两点和三点投篮趋势，并探讨其对比赛结果的影响。因此，考虑了以下与比赛相关的统计数据：场均得分（PPG）、比赛场次（GP）、命中的投篮数（FGM）、投篮尝试数（FGA）、投篮命中率（FG%）、命中的两分球数（2PM）、两分球投篮尝试数（2PA）、两分球投篮命中率（2P%）、命中的三分球数（3PM）、三分球投篮尝试数（3PA）、三分球投篮命中率（3P%）以及三分球与两分球的投篮比（3P/2P）。固定基指标和跨十年的 ANOVA 或 Friedman 检验被用作主要的统计工具。三分球投篮数随着时间的推移显著增加，而两分球投篮数则减少。三分球命中率也显著提高，而两分球命中率在分析期间相对稳定。本研究还揭示了在 NBA 比赛的最后十年，球权数和场均得分更高。
