【 摘 要 】
Although recommendations exist for determining qualitative sample sizes, the literature appears to contain few instances of research on the topic. Practical guidance is needed for determining sample sizes to conduct rigorous qualitative research, to develop proposals, and to budget resources. The purpose of this article is to describe qualitative sample size and sampling practices within published studies in education and the health sciences by research design: case study, ethnography, grounded theory methodology, narrative inquiry, and phenomenology. I analyzed the 51 most highly cited studies using predetermined content categories and noteworthy sampling characteristics that emerged. In brief, the findings revealed a mean sample size of 87. Less than half of the studies identified a sampling strategy. I include a description of findings by approach and recommendations for sampling to assist methodologists, reviewers, program officers, graduate students, and other qualitative researchers in understanding qualitative sampling practices in recent studies.URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1502256
