Procedures are described for standardizing outcomes in evaluations of service delivery systems. Accounting for the variability of a given device, client gains across services can be expressed in a standard metric of change. Standardized gains take on a common meaning of change regardless of the original scale and variability of the raw data. In return, a wide range of common statistical analyses can be applied with individual client gains as the units of analysis, powerfully delineating influences on outcome variability. Implications and limitations are discussed.
本文描述了在服务提供系统评估中对结果进行标准化的程序。考虑到给定设备的变异性，跨服务的客户收益可以用一个标准的变化指标来表示。标准化收益具有共同的变化含义，而不论原始数据的规模和变异性如何。作为回报，可以将广泛的常见统计分析应用于以个体客户收益为分析单位的情况，从而有力地描绘对结果变异性的影响。文中还讨论了其影响和局限性。
