Wilcoxon Example Matlab. The Wilcoxon rank sum test is equivalent to the Mann-Whitney U-test. If the median differs from the target the analyst uses the confidence interval to determine how large the difference is likely to be and whether that difference has practical significance.
We begin by calculating the ranks of the combined 24 raw scores using the supplemental RANK_AVG function or the standard RANKAVG function in Excel 2010. The Wilcoxon signed-rank test is a non-parametric statistical hypothesis test used to compare two related samples matched samples or repeated measurements on a single sample to assess whether their population mean ranks differ ie. If X and Y are independent samples with different sample sizes the test statistic which ranksum returns is the rank sum of the first sample.
The results of the Wilcoxon Rank-Sum test are displayed in Figure 3.
