Abstract: Based on past problems with data collection in experiments, experimental designers need a tool to assist in establishing effective experiments in which the data collection method minimizes the amount of data required and the data collection effort while maximizing the effectiveness and power of the data. A desktop tool, the Computer-Aided Design Reference for Experiments (CADRE), was developed for this purpose. The CADRE tool includes over 850 pages of reference material covering 25 topics, divided into five major sections, including an introduction to experimental design; supplemental data collection design and analysis; basic analysis of variance (ANOVA) designs; advanced ANOVA designs; and empirical model building. In addition, the CADRE tool contains over 200 pages explaining 40 examples of statistical analyses covered in the reference material and is hyperlinked to version 9.1.3 of the SAS statistical analysis package. Designers can use the CADRE tool to choose experimental design procedures to interrogate and build empirical models in support of complex studies, such as future command and control (C2) systems computer simulations.
