WebThe Wilcoxon signed ranks test is a nonparametric statistical procedure for comparing two samples that are paired, or related. The parametric equivalent to the Wilcoxon signed ranks test goes by names such as the Student’s t-test, t-test for matched pairs, t-test for paired samples, or t-test for dependent samples. WebRecall that when data are matched or paired, we compute difference scores for each individual and analyze difference scores. The same approach is followed in …
