Wilcoxon Signed-Rank

Calculates the Wilcoxon signed-rank statistics for dependent groups. The statistic w is calculated by building the difference between the two values of a pair and ranking them. The output will be the sum of ranks of positive differences (w+) and the sum of ranks of negative differences (w-) and the measures derived from that.

Options

Column pairs

Define the test column pairs here. Each pair is used to perform a Wilcoxon signed-rank test separately. The Wilcoxon signed-rank test compares two related samples by calculating the differences between paired values, ranking them, and determining whether the differences are statistically significant.

• Left column: Select the left column of the pair for comparison.
• Right column: Select the right column of the pair for comparison.

Calculate median values

Calculate the median values for each column in the column pairs. This option is computationally expensive for large datasets as it requires sorting the data.
