Production units for concentrating dilute acid are subject to failure as a result of corrosion. Seven units were selected from each of nine factories representing three groups according to the type of acid being concentrated. Productivity before failure was compared between type of acid and factory using doubly incomplete three-factor ANOVA that considers mean productivity across units, versus using UniODA that evaluates productivity of individual units.
