Abstract:

Daniel, in 1959, proposed the use of half-normal probability plots as a means of interpreting the results from unreplicated factorial experiments. zahn, in 1975, suggested modifications to Daniels approach and investigated some operating characteristics of the plots, along with techniques for estimating population sigma from the slope of the standardized contrasts plotted on half-normal probability paper. That work is reviewed here. This project examines some properties and the usefulness of both normal and half-normal probability plots when applied to the intrepertation of experiment is to select from a very large number of potentially critical factor the ones that do have an important effect on the performance of a particular task, so that these may be investigated in depth.
