Wilcoxon Signed Rank Test Calculator The Wilcoxon Signed Rank test is a non-parametric test used to determine whether two dependent/matched groups of data are different. A good example would be the blood sugar level of a group of patients before a particular drug is applied, and the blood sugar level of the same group of patients just after the treatment. Wilcoxon Signed-Ranks Test for Paired Samples. When the requirements for the t-test for two paired samples are not satisfied, the Wilcoxon Signed-Rank Test for Paired Samples non-parametric test can often be used. In particular, we assume n subjects from a given population with two observations x i and y i for each subject i. This free online software (calculator) computes various types of parametric and non-parametric tests for comparing the means of two paired or unpaired samples: classical Paired Two Sample t-Test, classical Unpaired Two Sample t-Test, Welch t-Test, Wilcoxon Signed-Rank Test, and Wilcoxon Rank-Sum Test (Mann-Whitney U Test). Wilcoxon Rank Sum Test for Independent Samples When the requirements for the t-test for two independent samples are not satisfied, the Wilcoxon Rank-Sum non-parametric test can often be used provided the two independent samples are drawn from populations with an ordinal distribution. For this test we use the following null hypothesis: The Wilcoxon Rank Sum Test is often described as the non-parametric version of the two-sample t-test. You sometimes see it in analysis flowcharts after a question such as “is your data normal?” A “no” branch off this question will recommend a Wilcoxon test if you’re comparing two groups of continuous measures.
