First, we hoped to turn an area of study that students generally ﬁnd daunting and feel anxious about into something that makes sense and with which they can begin to feel conﬁdent. Principles of Experimental Design Bret Hanlon and Bret Larget Department of Statistics University of Wisconsin|Madison November 15, 2011 Designing Experiments 1 / 31 Experimental Design Many interesting questions in biology involve relationships between response variables and one or more explanatory variables. The design of experiments (DOE, DOX, or experimental design) is the design of any task that aims to describe and explain the variation of information under conditions that are hypothesized to reflect the variation.The term is generally associated with experiments in which the design introduces conditions that directly affect the variation, but may also refer to the design of quasi-experiments, in which … Experimental Design and Statistics Steve Miller SECOND EDITION London and New York.
