This article describes how to perform Wilcoxon signed-rank test comparing the median between a pair of samples.

For samples of different sizes see How to Perform Two-Sample Wilcoxon Rank Sum Test.

## Requirements

A Displayr **document** with a **data set**.

## Method

- Go to
**Anything > Advanced Analysis > Test > Nonparametric > Paired Samples Wilcoxon Test**. - Specify the two input variables under
**Inputs > Paired Samples Wilcoxon Test > Variable 1**and**Variable 2**.

OPTIONAL: Adjust any other options and settings as required.

**mu**- Difference between the median of the two samples, as assumed under the null hypothesis.**Alternative hypothesis**- Use a two-sided or one-sided test.**Type of test**- Method by which the p-value is computed.**Output****Summary**- Shows a nicely formatted table of the test results (default).**R**- The original text-based output from the`wilcox.test`function.

**Variable names**- Display Variable Names in the output, instead of Variable Labels.**More decimal places**- Display numeric values with 8 decimal places.
