给出了以群体而非个体为随机化单位的配对干预试验的统计威力计算公式。还研究了影响此类试验功效的因素，并给出了将组随机化功效与个体随机化功效进行比较的例子。
A formula is given for the calculation of the statistical power of paired intervention trials in which the units of randomization are groups rather than individuals. Factors affecting the power of such trials are also investigated and an example is given where the power of group randomization is compared to that of individual randomization.
