Abstract: Controlled experiments give researchers a statistical tool for determining the yield from subjecting an experimental unit to various treat ments. We will discuss a replicated, block design applied to the experimental unit yeast. We subjected the yeast to six treatments. The purpose of the experiment is to extract a compound to be used in the manufacturing in dustry. We considered an ANOVA and a MANOVA model to analyze the data. The rationale for selecting one model over the other will be discussed. Results and recommendations of which treatments to use when processing the yeast will be presented, also.
