ABSTRACT
The concept of restriction on randomization for the blocks introduced in Chapter 5 on the RCBD is extended in the use of split plot designs. Actually there can be many restrictions on randomization at various levels in experimentation that will cause many “splits” in the design. These designs are sometimes called split-split plot, split-split-split plot and so on. The general split plot type designs with their associated restrictions on the randomization are considered in this chapter. For all cases covered in this chapter we assume that the effects of any correlation among errors on the analyses given is negligible.
