Design of experiments

Industrial Engineering

Design of experiments is a statistical methodology for constructing procedures that test how changes to one part of a system affect other parts of it, distinguishing the variables that are deliberately changed from those that must be held constant. It aims to produce results with proper validity, reliability and reproducibility, and is applied across the natural sciences, social sciences and engineering, including in quality by design frameworks. Charles Sanders Peirce laid early groundwork for the field in the 1870s and 1880s by stressing randomization and running one of the first randomized, blinded experiments. Ronald Fisher formalized experimental design as a discipline in his books The Arrangement of Field Experiments and The Design of Experiments, drawing on agricultural research.
