A Randomized Block Design is used to compare fleece weights of three breeds of sheep – Merino, Suffolk, and Dorset (we can think of the three breeds as being the three treatments). The sheep are divided into two weight classes (i.e., two blocks). Block one contains sheep weighing less than 150 lb and block two contains sheep weighing more than 150 lb. The fleece weights (in pounds) are as follows: Merino Suffolk Dorset Block 1 13 8 9 Block 2 14 9 11 The partially completed ANOVA table for this experiment is as follows: Source df SS MS F Total 29.33333 Breed 26.33333 13.16667 79.00003 Block Error 0.33333 0.16667 The correct degrees of freedom for total, breed, block, and error, respectively are:
