Use experimental design techniques to both improve a process and to reduce output variation. Experimental Design Short Report Form: The short form is often used for quick labs that are teaching something other than experimental design, or for a beginning-of-the-year review of the basics of experimental design. • Takes advantage of grouping similar experimental units into blocks or replicates. More about Single Factor Experiments † 3. Before examining specific experimental designs and the way that their data are analyzed, we thought that it would be a good idea to review some basic principles of statistics. Good design con-cepts are best illustrated by examples, so we provide many in this chapter, mostly involving clinical trials or improving education in developing countries. Factorial Designs † 5. Experimental studies done some thousand of years ago prove that unrefined apparatus and limited knowledge, we were already trying to answer the questions of the universe.
