作者阐述了小群体数据的统计分析中固有的复杂性和机会。他们开始讨论组成员得分的非独立性，然后考虑分析单组数据的标准方法，并确定这些方法没有考虑这种非独立性。提出了一种新的方法，使用多层次建模，并允许负非独立性和相互影响。终于来了考虑了相互作用的复杂性、不同的群体规模和差异效应。作者强烈要求，小组研究数据的分析模型应该反映产生这些数据的心理过程。
The authors elaborate the complications and the opportunities inherent in the statistical analysis of small-group data. They begin by discussing nonindependence of group members' scores and then consider standard methods for the analysis of sinall-group data and determine that these methods do not take into account this non independence. A new method is proposed that uses multilevel modeling and allows for negative nonindependence and mutual influence. Finally. the complications of interactions, different group sizes, and differential effects are considered. The authors strongly urge that the analysis model of data from small-group studies should mirror the psychological processes that generate those data.
