Overview for Pairwise Averages

Use Pairwise Averages (also called Walsh averages) to calculate and store the means of each possible pair of values in your data set, including the pair of each value with itself. For example, the data set {1, 3} has three pairs: 1 paired with itself, 1 paired with 3, and 3 paired with itself. The pairwise averages are the means of these pairs. So this data set has three pairwise averages: 1, 2, and 3. Pairwise averages are used, for example, for the Wilcoxon method.

Where to find this analysis

To perform pairwise averages, choose Stat > Nonparametrics > Pairwise Averages.
