Practical issues in survey sampling.
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.
