Wilcoxon Signed-Rank Test using SPSS Statistics Introduction The Wilcoxon signed-rank test is the nonparametric test equivalent to the dependent t-test. As the Wilcoxon signed-rank test does not assume normality in the data, it can be used when this assumption has been violated and the use of...
Assumption #3 relates to the nature of your data and can be checked using Minitab. You have to check that your data meets this assumption because if it does not, the results you get when running a Wilcoxon signed-rank test might not be valid. In fact, do not be surprised if your dat...
