Wilcoxon Signed-Rank Test Calculator

The Wilcoxon Signed-Rank Test is the non-parametric version of the paired t-test. It is used to test whether or not there is a significant difference between two population means.
To perform a Wilcoxon Signed-Rank Test, simply fill in the data values for two samples below and then click the “Calculate” button.

Sample 1

Sample 2

W test statistic = 29.5

Number of non-tied pairs (n) = 13

Refer to the critical values table below to decide whether or not the test result is statistically significant based on n and your chosen alpha level.

If the test statistic W is less than the value found in the critical values table below, then the test result is statistically significant.

  1. In your Wilcoxon Signed-Rank Test Calculator
    The number of non-tied pairs (n) stays 13 when I put on more numbers

    I have 235 pairs, can I use the test?

  2. I really appreciate the excellent dashboard, having done the Excel tutorial to calculate the Wilcoxon Signed-Rank Test and then using the calculator, helped me greatly to understand the purpose and the calculation process. Can Statology be cited in an academic paper? If so, could you tell me how the reference should be?
    Thanks again

  3. Hi, I’m kind of a dope about this stuff and it will not stay in my head.
    I taught a class with the pre and post eval a Likert type scale 1-10 and an n of 7
    I enter the series of responses (sample 1) in your first box and the post test responses in the same order participant responses that were in the first box (hope that makes sense)
    1. Is that right? I find a w test stat of 0 telling me there is a statistical difference between pre and post test.
    2. How do I write this up–what is the language? I’m publishing a paper and want to at least pretend I know what I’m saying.

  4. not able to use it as it was not performing when Calculate, in spite of attempting many times
