本文介绍了一个随机数字拨号电话调查的效率，收集健康态度信息的调查。数据来自1976-77年猪流感免疫运动期间对密歇根州奥克兰县成年人进行的一项调查。信息的结果，拨号到样本的电话号码，在样本内的非工作号码的频率，从未回答过的号码的问题，和样本估计的精度。此外，还提出了一些粗略的费用估计数，并与其他研究报告中报告的调查费用进行了比较。研究结果显示，随机数字拨号是一个有效的调查方法，无论是在实施成本和抽样精度。
This paper describes an investigation into the efficiency of a random-digit-dialed telephone survey for the collection of health attitude information. Data come from a survey of adults in Oakland County, Michigan, conducted during the 1976–77 swine influenza immunization campaign. Information is presented on the results of dialing to sample telephone numbers, the frequency of nonworking numbers within the sample, problems with numbers that were never answered, and precision of sample estimates. In addition, some rough estimates of cost are presented and compared to survey costs reported in other studies. Findings suggest that random digit dialing is an efficient survey method, both in terms of cost in implementation and sampling precision.
