ABSTRACT

Experimental design, the way the experiment is to be set up, is a critical factor in the generation of experimental data. Several designs may serve a particular need, but there will be one that is more applicable to the problem, better suited to the conditions under which the experiment is going to be conducted, provides required precision and is most efficient in the use of the research resources. If the design of the experiment is not properly related to the problem orientation of the project it will not determine relationships useful to problem resolution. The ultimate size and complexity of an experiment depends on many factors including number of independent factors to be controlled or measured, analytical techniques to be used, statistical precision required, quantity and quality of prior information available, the objectives of the research project, the time within which results must be obtained, and the resource constraints encompassing the project.
