关于定性研究中抽样的一个常见误解是，在确保抽样策略的充分性方面，数字是不重要的。然而，简单的规模可能太小，不足以支持已经实现信息冗余或理论饱和的主张，或者太大，无法进行深入的，面向案例的分析，这是定性调查的存在理由。在定性研究中确定适当的样本量最终是一个判断和经验问题，即评估收集到的信息的质量，将其用于何种用途，所采用的特定研究方法和有目的的抽样策略，以及预期的研究产品。(C) 1995 John Wiley & Sons, Inc.；
A common misconception about sampling in qualitative research is that numbers are unimportant in ensuring the adequacy of a sampling strategy. Yet, simple sizes may be too small to support claims of having achieved either informational redundancy or theoretical saturation, or too large to permit the deep, case-oriented analysis that is the raison-d'etre of qualitative inquiry. Determining adequate sample size in qualitative research is ultimately a matter of judgment and experience in evaluating the quality of the information collected against the uses to which it will be put, the particular research method and purposeful sampling strategy employed, and the research product intended.
