Conduct a Friedman Test in Excel

When to Use the Friedman Test

A Friedman test is one of the many non-parametric statistical tests performed by QI Macros Add-in for Excel. It is like a two-way ANOVA.

 

Note: Excel does not do statistical tests of non-normal (i.e., not "bell shaped") data. QI Macros, adds this functionality with a set of of non-parametric test templates.

Example of a Friedman Test Using QI Macros Template for Excel

A pharmacutical company wants to compare the reaction time for four drugs (A-D). Each drug is given to five subjects and reaction time is measured. The null hypothesis is that reaction times for the four drugs are the same.

  1. Click on QI Macros menu, Statistical Templates to open the non-parametrics test template. Then click on the Friedman tab.
  2. Input your data into the yellow shaded cells.
  3. QI Macros will perform the calculations for you.

Interpreting the Results: Since p (0.989) is greater than alpha (0.05), we cannot reject the null hypothesis that the reaction times are the same.
