摘要

诸如t检验之类的参数检验需要数据的正态分布。然而，在处理小样本量时，正态分布的确定可能不是决定性的。这种情况下可以使用非参数检验，如Wilcoxon检验，因为这些检验不需要正态分布。

“Selection of statistical tests influences the interpretation of a study outcome” a comment on “Giriraja KV, Bhatnagar SK, Tomlinson L, Sancilio F. An open-label, multicenter, phase 2 study of a food enriched with docosahexaenoic acid in adults with sickle cell disease. Prostaglandins Leukot Essent Fatty Acids. 2023 Jun; 193:102574. Doi: 10.1016/j.plefa.2023.102574. Epub 2023 Apr 7. PMID: 37121179”

Parametric tests such as t-tests require a normal distribution of data. However, the determination of normal distribution may not be conclusive while dealing with a small sample size. Non-parametric tests such as Wilcoxon tests may be used in this situation, as these tests do not require normal distribution.
