Experiment Design Analysis - Manure I

Farmer Fred wants to see what is the best manure to spread on his fields. He has three types of manure; cow, hog and chicken. He divides his field into three areas. The areas are of equal size. He spreads the same amount of manure on each area and grows oats on all three areas. In the fall for each area, Farmer Fred measures how many bushels of oats he harvested and which oats made the best tasting oatmeal.
