Explain the Randomized Block Design
-A farmer wishes to test the effects of a new fertilizer on her tomato yield. She has four equal-sized plots of land-- one with sandy soil, one with rocky soil, one with clay-rich soil, and one with average soil. She divides each of the four plots into three equal-sized portions and randomly labels them A, B, and C. The four A portions of land are treated with her old fertilizer. The four B portions are treated with the new fertilizer, and the four C s are treated with no fertilizer. At harvest time, the tomato yield is recorded for each section of land. What is the treatment in this experiment
A) the fertilizers
B) the tomato yield recorded for each section of land
C) the section of land (A, B, or C)
