We propose a new sequential hypothesis testing procedure in which data are collected and analyzed in a series of independent segments. As in fixed-sample hypothesis testing and in previous sequential procedures, the overall α level can be set to any desired value. Like other sequential procedures, the independent segments procedure generally requires smaller samples than fixed-sample procedures-often approximately 30% smaller-to achieve the same α level and statistical power. Relative to other sequential procedures, the new method has the advantages that it is simpler to use, requires fewer assumptions, and can be used with a wider array of statistical tests. Thus, in some circumstances the independent segments procedure may provide an attractive option for increasing the efficiency of statistical testing.

我们提出了一种新的序贯假设检验程序，其中数据以一系列独立的片段进行收集和分析。与固定样本假设检验和之前的序贯程序一样，可以将总体α水平设置为任何所需的值。与其他序贯程序一样，独立片段程序通常需要比固定样本程序小的样本量——通常小约 30%——才能达到相同的α水平和统计功效。与其他序贯程序相比，新方法具有使用更简单、假设要求更少以及可用于更广泛的统计检验的优点。因此，在某些情况下，独立片段程序可能是一种增加统计检验效率的有吸引力的选择。（PsycInfo 数据库记录（c）2021 APA，保留所有权利）。
