Wilcoxon Test Minitab. 201 - The Sign Test for a Median 201 - The Sign Test for a Median. The p-value for the Wilcoxon test is 0036 so we reject the null hypothesis and conclude that the difference is not equal to 0.
Wilcoxon Rank Sum Test Minitab does a twosample rank test often called the MannWhitney test or the twosample Wilcoxon rank sum test for the difference between two population medians and calculates the corresponding point estimate and confidence interval. Minitab uses the Wilcoxon statistic to calculate the p-value which is a probability that measures the evidence against the null hypothesis. Key output includes the estimate of the median the confidence interval and the p-value.

Because the interpretation of the Wilcoxon statistic depends on the sample size you should use the p-value to make a test decision.
