Affinity diagram

A tool used to gather and group ideas. Usually depicted as a "tree" diagram.

ANOM

Analysis of the Mean. An analytical process that quantifies the mean response for each individual control factor level. ANOM can be performed on data that is in regular engineering units or data that has been transformed into some form of signal-to-noise ratio or another data transform. Main effects and interaction plots are created from ANOM data.

ANOVA

Analysis of the variance. An analytical process that decomposes the contribution each control factor has to the overall experimental response. The ANOVA process also can account for the contribution of interactive effects between control factors and experimental error in the response, provided that enough degrees of freedom are established in the experimental array. The value of epsilon squared (the % contribution to the overall CFR variation) is calculated using data from ANOVA.
