Abstract

In qualitative comparative analysis, as with all methods, there is a question about how many cases are needed to make an analysis robust. In deciding on the number of cases, a key consideration is the number of conditions to be analyzed. I suggest that adding cases is preferable to dropping conditions if there are too many conditions relative to the number of cases. I first consider the relationship of low n and limited diversity, followed by an exploration of two scenarios: (1) cases in the study are the universe; (2) more cases could exist. I suggest that a simple rule or benchmark on how many cases to include in relation to the number of conditions is unlikely to be helpful since this depends at least in part on the goals and circumstances of the research. Finally, this issue is not confined to QCA but affects all types of research.

定性比较分析中的病例与条件比率：添加病例而不是删除条件

与所有方法一样，在定性比较分析中也存在一个问题，即需要多少案例才能使分析稳健。在决定案例数量时，一个关键的考虑因素是要分析的条件的数量。我建议，如果相对于案例数量而言条件过多，增加案例比放弃条件更可取。我首先考虑了低 n 与有限多样性之间的关系，然后探讨了两种情况：(1) 研究中的案例就是宇宙；(2) 可能存在更多案例。我认为，关于根据条件的数量纳入多少案例的简单规则或基准不太可能有帮助，因为这至少部分取决于研究的目标和情况。最后，这个问题并不局限于 QCA，而是影响到所有类型的研究。

期刊介绍： Field Methods (formerly Cultural Anthropology Methods) is devoted to articles about the methods used by field wzorkers in the social and behavioral sciences and humanities for the collection, management, and analysis data about human thought and/or human behavior in the natural world. Articles should focus on innovations and issues in the methods used, rather than on the reporting of research or theoretical/epistemological questions about research. High-quality articles using qualitative and quantitative methods-- from scientific or interpretative traditions-- dealing with data collection and analysis in applied and scholarly research from writers in the social sciences, humanities, and related professions are all welcome in the pages of the journal.
