Worksheet details
By default, the worksheet randomizes samples within each appraiser. In this case, Minitab randomizes the 50 samples separately for Alex, Nina, David, and Wendy. In the second trial, the appraiser pattern repeats with each set of 50 measurements completely re-randomized for each appraiser.
The worksheet is ready for you to enter the data into the Assessments column with the same codes that you used in the Standard column (A or R).
