Store your results for Friedman Test

Stat > Nonparametrics > Friedman

You can save statistics from your analysis to the worksheet so that you can use them in other analyses, graphs, and macros. Minitab stores the selected statistics after the last column of data. The names of the storage columns end with a number that increases as you store the same statistic multiple times.
Store residuals
The residuals are calculated as (the observation adjusted for treatment effect) – (the adjusted block median). Minitab stores the residuals in the column RESI1.
Store fits
The fitted values are calculated as (the treatment effect) + (the adjusted block median). Minitab stores the fitted values in the column FITS1.
