Using JMP to Randomly Assign Treatments to Plots
and to Analyze the Resulting Data
1. Number the plots from 1 to 36 starting at the upper left hand corner and going
from left to right. At the end of each row go to the next row and continue
numbering from left to right.

2. Create a new JMP data table with two columns each with 36 rows. Label the first
column Plot and the second column Variety. Put A in the first 18 rows of the
Variety column and B in the other 18 rows of the Variety column. For the Plot
Number column use Col – Formula – Random – Col Shuffle.

5. Use JMP: Analyze – Fit Y by X; Y, Response is Yield and X, Factor is Variety.
