The Mann-Whitney Test is a hypothesis test that determines whether a statistically significant difference exists between the medians of two independent sets of non-normally distributed continuous data. Complete the following steps to interpret a Mann-Whitney test. Key output includes the estimate for difference, the confidence interval, and the p-value. Interpret the key results for Mann-Whitney Test - Minitab . Minitab uses the Mann-Whitney statistic to calculate the p-value, which is a probability that measures the evidence against the null hypothesis. Because the interpretation of the Mann-Whitney statistic depends on the sample size, use the p-value to make a decision about the test. The p-value has the same meaning for any sample size.

Nonparametric Tests Wilcoxon Rank Sum Test Minitab does a two‐sample rank test (often called the Mann‐Whitney test or the two‐sample Wilcoxon rank sum test) for the difference between two population medians, and calculates the corresponding point estimate and confidence interval. The Mann-Whitney test does not always achieve the confidence interval that you specify because the Mann-Whitney statistic (W) is discrete. Minitab calculates the closest achievable confidence level. The achieved confidence indicates how likely it is that the population difference is contained in the confidence interval. Complete the following steps to interpret a Mann-Whitney test. Key output includes the estimate for difference, the confidence interval, and the p-value. Interpret the key results for Mann-Whitney Test - Minitab .

How to Run a Mann-Whitney Test in Minitab. 1. Select Raw Data. If that assumption does not hold, the nonparametric Mann-Whitney test is a better for percent confidence interval for ETA1 – ETA2 is (;). The Mann-Whitney U-test isn't actually a test of the median, never used Minitab , but it appears to me that you may have run a one-tailed test. The official performs a Mann-Whitney test to determine whether the median The Percent CI indicates that the population median of Brand B is likely to be. The Two Sample t-Test and the Wilcoxon–MANN–Whitney Test Minitab elsewhere says that “If sampling from nonnormal .. example, the area under the ROC curve is with 95% confidence interval (, ). In Minitab the estimated medians for the two samples are calculated, The Mann -Whitney Test using Minitab Mann-Whitney Confidence Interval and Test. Interpretation. The sample size affects the confidence interval and the power of the test. Usually, a larger sample size results in a narrower confidence interval.
