ABSTRACT
Many agricultural experiments involve the use of a single-factor experimental design. In this type of design, a single factor varies while all other factors are held constant. For example, when an agronomist is interested in finding whether one variety is superior to another, he or she will use a single-factor experiment in which the single variable factor is the variety, and the treatments or factor levels are different variables. In such an experiment, all cultural practices — water, fertilizer application, pest control, and other management activities — remain the same.
