... consistently in a shop trial (e.g., a surface flaw). Ross ( Ref 3 ) describes how the analysis of variance (ANOVA) with orthogonal arrays (OAs) may be used to rank the importance of independent variables—OAs are used for design of a fractional factorial experiment (FFE). Analysis of variance finds the...
