本文是一个实用的指南（工具包），为研究人员，学生和从业人员希望引入随机化的一部分，在该领域的研究设计。它首先涵盖了使用随机化的基本原理，作为选择偏倚的解决方案和发表偏倚的部分解决方案。其次，它讨论了各种方式，其中随机化可以实际引入一个字段设置。第三，讨论了样本量要求、分层、随机化水平和数据收集方法等设计问题。第四，它讨论了如何分析数据从随机评价时，有偏离的基本框架。它特别审查了如何处理不完美的遵守和外部性。最后，它讨论了从随机评价中得出一般性结论所涉及的一些问题，包括在设计评价和解释结果时必须使用理论作为指导。
This paper is a practical guide (a toolkit) for researchers, students and practitioners wishing to introduce randomization as part of a research design in the field. It first covers the rationale for the use of randomization, as a solution to selection bias and a partial solution to publication biases. Second, it discusses various ways in which randomization can be practically introduced in a field settings. Third, it discusses designs issues such as sample size requirements, stratification, level of randomization and data collection methods. Fourth, it discusses how to analyze data from randomized evaluations when there are departures from the basic framework. It reviews in particular how to handle imperfect compliance and externalities. Finally, it discusses some of the issues involved in drawing general conclusions from randomized evaluations, including the necessary use of theory as a guide when designing evaluations and interpreting results.
