This discussion reviews the principles of survey sampling and applies these principles in a study examining nurses' skills (N = 15,540). Three major facets of sampling are outlined-the sample frame, the sample size and the specific design of the selection procedures. The characteristics of a sample frame, precision in sample size estimation, and rules to be used in the selection procedures, are outlined. In addition, the authors recommend how to obtain assistance with these complex procedures and some steps in problem-solving. This paper provides guidance that will enable nurse researchers, using survey methods, to obtain sample estimates that closely resemble the population.
本讨论回顾了调查抽样的原则，并将这些原则应用于一项对护士技能的研究（N = 15540）。抽样的三个主要方面被概述——抽样框、样本量和选择程序的具体设计。文中概述了抽样框的特征、样本量估计的精度以及选择程序中应使用的规则。此外，作者还推荐了如何在这些复杂程序上获得帮助以及一些解决问题的步骤。本文提供的指导将使采用调查方法的护士研究人员能够获得与总体非常相似的样本估计。
