The matching law was used to analyze whether the proportion of shots taken from two- or three-point range would match the proportional reinforcement rates produced by those shots when the reinforcement rate of three-point shooting was changed. Rule changes in 1994 and 1997 altered the distance of the three-point line in the National Basketball Association, which created a quasiexperimental reversal design, thereby naturally changing three-point reinforcement rates. The present data partially confirmed predictions made by the matching law, in that increases in the relative rate of three-point shots attempted corresponded to increases in the relative rate of three-point shots made.
匹配法则被用于分析当三分球投篮的强化率发生变化时，来自两分或三分线外投篮的比例是否会与这些投篮产生的比例强化率相匹配。1994年和1997年的规则变化改变了美国职业篮球联赛（NBA）三分线的距离，这创造了一种准实验性的反转设计，从而自然地改变了三分球的强化率。目前的数据部分证实了匹配法则所做的预测，即尝试三分球的相对率增加与命中三分球的相对率增加相对应。
