Added summary of difference between wilcoxon signed rank test and wilcoxon rank sum test (copied and pasted from the article on wilcoxon rank sum test)
Line 1: Line 1:
The '''Wilcoxon signed-rank test''' is a [[Non-parametric statistics|non-parametric]] [[statistical hypothesis testing|statistical hypothesis test]] used when comparing two related samples, matched samples, or repeated measurements on a single sample to assess whether their population mean ranks differ (i.e. it is a [[paired difference test]]). It can be used as an alternative to the [[Student's t-test|paired Student's t-test]], ''t''-test for matched pairs, or the ''t''-test for dependent samples when the population cannot be assumed to be [[normally distributed]].<ref name=lowry>{{cite web|last=Lowry|first=Richard|title=Concepts & Applications of Inferential Statistics|url=http://faculty.vassar.edu/lowry/ch12a.html|accessdate=24 March 2011}}</ref>

The Wilcoxon signed-rank test is not the same as the [[Wilcoxon rank-sum test]], although both are nonparametric and involve summation of ranks.
The Wilcoxon signed-rank test is not the same as the [[Wilcoxon rank-sum test]], although both are nonparametric and involve summation of ranks.The Wilcoxon rank-sum test is applied to independent samples. The Wilcoxon signed-rank test is applied to matched or dependent samples.
