WebSuppose we want to determine whether there is a significant difference in the yield of three types of seed for cotton (A, B, C) based on planting seeds in 12 different plots of land. With a completely randomized design (CRD) we can randomly assign the seeds as follows: Each seed type is assigned at random to 4 fields irrespective of the farm.
