Write out the design and contrast matrices for:
( For ease I am putting grids on this sheet, you may not need to use the entire grid)
1.
2.
3.
4.
CRD with one Factor 4 levels (2 reps each)
We are interested in comparing 1 and 3
Comparing 2 to the mean 3 and 4
Comparing 1 to the mean of 2, 3 and 4.
2. CRD with two Factor (A,B) one with 4 levels and the other with 2 levels (2 reps each)
a. We are interested in comparing 1 and 3 (factor 1)
b. Comparing 1 and 2 (factor 2)
c. Comparing A1B1 to the mean of A3B1 and A3B2
