BACKGROUND
There is confusion in the medical literature as to whether statistics should be reported in survey studies that query an entire population, as is often done in educational studies. Our objective was to determine how often statistical tests have been reported in such articles in two prominent journals that publish these types of studies.
METHODS
For this observational study, we used electronic searching to identify all survey studies published in Academic Medicine and the Journal of General Internal Medicine in which an entire population was studied. We tallied whether inferential statistics were used and whether p-values were reported.
RESULTS
Eighty-four articles were found: 62 in Academic Medicine and 22 in the Journal of General Internal Medicine. Overall, 38 (45%) of the articles reported or stated that they calculated statistics: 35% in Academic Medicine and 73% in the Journal of General Internal Medicine.
CONCLUSION
Educational enumeration surveys frequently report statistical tests. Until a better case can be made for doing so, a simple rule can be proffered to researchers. When studying an entire population (e.g., all program directors, all deans, and all medical schools) for factual information, do not perform statistical tests. Reporting percentages is sufficient and proper.
背景
在医学文献中，对于像教育研究中经常对全体人群进行询问的调查研究是否应报告统计数据存在困惑。我们的目的是确定在发表此类研究的两种著名期刊上，这类文章中报告统计检验的频率。
方法
对于这项观察性研究，我们通过电子检索来识别发表在《学术医学》和《普通内科医学杂志》上的所有对全体人群进行研究的调查研究。我们统计是否使用了推断性统计以及是否报告了p值。
结果
共找到84篇文章：《学术医学》上有62篇，《普通内科医学杂志》上有22篇。总体而言，38篇（45%）文章报告或表明他们计算了统计数据：《学术医学》上为35%，《普通内科医学杂志》上为73%。
结论
教育普查经常报告统计检验。在能提出更好的理由之前，可以向研究人员提供一条简单规则。当研究全体人群（如所有项目主任、所有院长和所有医学院）以获取事实信息时，不要进行统计检验。报告百分比就足够且恰当。
