Employing Randomized Experiments in Sample Surveys

该研究将证明在抽样调查中定期纳入随机实验如何有助于分析和解释调查数据。一些实验将利用正式的方法问题，例如开放式和封闭式问题之间的区别，而另一些实验将改变问题的内容，以便在特定的实质性领域探索这些问题。第三组实验将处理在可能引起争议的话题中不同形式的提问的影响。在整个过程中，目的将是检验实验方法和调查方法合并的容易程度和有效性，以及合并后的方法在实质性分析中的有用性。

The research will demonstrate how the regular inclusion of randomized experiments in sample surveys can aid in the analysis and interpretation of survey data. Some experiments will draw on formal methodological issues, such as the difference between open and closed questions, while others will vary the content of questions in order to explore these issues in a particular substantive area. Still a third set of experiments will deal with the effects of different forms of questioning in the case of topics likely to elicit controversy. Throughout, the aim will be to test the ease and efficacy with which experimental and survey methods can be merged, and the usefulness of the resultant combination in substantive analysis.
