To determine if we should reject or fail to reject the null hypothesis, we can find the critical value that corresponds to α = .05 and a sample size of 11 in the following Wilcoxon Signed Rank Test Critical Values Table: The critical value that corresponds to α = .05 and a sample size of 11 is 10. Since the test statistic (10.5) is not less ...
The Wilcoxon Signed-Rank Sum test is the non-parametric alternative to the dependent t-test. The Wilcoxon Signed-Rank Sum test compares the medians of two dependent distributions. The Signed-Rank Sum test, developed by Frank Wilcoxon, finds the difference between paired data values and ranks the absolute value of the differences.
The Wilcoxon Signed Rank Test calculator provides the Wilcoxon statistics and critical value for two groups of numeric observations based on an alpha value and whether it's a one or two tailed test.
To use this table: compare your obtained value of Wilcoxon's test statistic to the critical value in the table (taking into account N, the number of subjects). Your obtained value is statistically significiant if it is equal to or SMALLER than the value in the table. e.g.: suppose my obtained value is 22, and I had 15 participants.

Statology makes learning statistics easy by explaining topics in simple and straightforward ways. Our team of writers have over 40 years of experience in the fields of ...
Wilcoxon Signed-Ranks Test; ... We look up our critical value in the z-Table and find a critical value of plus/minus 1.96. If z is less than -1.96, or greater than 1.96, reject the null hypothesis. ... First, we must find the difference scores for our two groups: Figure 3. Next, we rank the difference scores. Then, we add up the rankings of ...
The Wilcoxon Signed-Rank test is a nonparametric test, it compares Interval scale data for a significant difference between two dependent groups. The test finds the differences of the two groups. ... Critical Value Check the the two tails statistic table, for α = 0.05, n = 12. Critical W is 13. P-value; For α=0.02, critical W is 9.
The Wilcoxon Signed Rank Test Critical Values Table is a key tool for interpreting the results of the Wilcoxon Signed Rank Test, a non-parametric statistical test used to compare two related samples. Here’s a breakdown of the table and its explanation: What it contains:

Reject the null hypothesis if the test statistic T is less than or equal to the critical value found in this table.
Wilcoxon Signed-Rank Test. The logic and computational details of the Wilcoxon test are described in Subchapter 12a of Concepts and Applications. ... For smaller sample sizes (n s/r = 5 through 9), the obtained value of W can be referred to the separate table of critical values of ...
Critical Values for T in theWilcoxon Signed Mixed-Pairs Signed-Rank Test The values below are the approximate critical values of T for two-tailed tests at level P. For a signicant result, the calculated T must be less than or equal to the tabulated value. (Values of P are halved for one-tailed tests using R− and R+.) n P = 0.10 P = 0.05 5 2 ...
