ABSTRACT
The completely randomized design (CRD), the randomized complete block design (RCBD) and the split plot designs are used more frequently in experimentation than the designs in this chapter. The Latin square (LS) and other designs similar to it are used by some research workers, but are misused by others more frequently. Hence in this chapter we will try to point out the type of experimental problems in which these designs are appropriate and the mistakes that experimenters may make if these designs are not handled correctly.
