Document Summary

We study the e ects of two or more factors, each at several levels. A factorial design has obser- vations at all combinations of these levels. 2 ; = 2 levels of factor a) and their lifetimes may depend on the temperature at which they are used (lo = 1 , hi= 2 ; = 2 levels of factor. = 4 observations are made at each of the. = 16 observations are made in random order, so this is also a crd. We see the e ect of changing one factor, while leaving the other xed, by plotting the means at the 4 combinations. 104 y
