Citation: Francis Sahngun Nahm (2016), “Nonparametric statistical tests for the continuous data: the basic concept and the practical use”, Korean Journal of Anesthesiology, 69(1), 8-14, DOI: 10.4097/kjae.2016.69.1.8.
What does this resource offer: The author discusses nonparametric statistical methods and their comparability to parametric methods for small sample sizes, which is very applicable to medical research questions. The article includes:
- a brief history of nonparametric statistical analysis,
- a clear description of the basic principles of nonparametric statistical analysis,
- an excellent explanation of the advantages and disadvantages of nonparametric statistical methods, and
- helpful examples for each nonparametric statistical test discussed.
This article is probably best suited for those who have already had some exposure to basic parametric statistical methods (such as t-tests) via a formal class or an in-depth workshop.
