ABSTRACT
Up until this point, all of the experiments (utilizing ANOVA [analysis of variance]) we have examined have dealt with a single experimental factor whether varieties, fertility levels, etc. It is possible to conduct experiments in which more than one experimental factor at a time is considered. In fact, in most biological systems, there are several factors in play at any one time. Conducting experiments with more than one factor is more likely to mimic real environmental conditions and allows the researcher to see how these factors interact with one another. In addition, time and resources may be conserved because more than one factor is considered in a single experiment.
