Principles of Experimental Design,scussion of some key ideas of experimental design, including the role of randomization, replication, and the basic idea of blocking for increasing precision and power. We also take a more high-level view and consider the construct, internal and external validities of an experiment, and the correspon

Planning for Precision and Power, size of treatment groups, and methods for increasing precision and power by blocking or sub-sampling that do not require increasing the sample size. We then discuss the determination of sample sizes to achieve the desired precision of a difference of means, and the problem of power analysis for tes

Split-Unit Designs,ds to different precision of estimates and power of tests, but can have advantages when some treatments are more easily changed than others. We discuss the basic split-unit design in detail and introduce several related designs, such as a split-unit blocked on the whole-unit level, simple cross-over
