Methods, systems and computer readable media for producing a metric to characterize a chemical array. Effects of terms impacting results of measurement of an output generated from analysis of the array or a procedure performed using the array, are quantified by performing ANOVA analysis and calculating sums of squares quantities attributable to each of the terms respectively. A metric is derived from at least two of the calculated sum of squares quantities. Methods systems and computer readable media for characterizing one or more chemical arrays may perform the steps of querying a database storing sums of squares quantities quantifying effects of terms impacting results of measurements of outputs generated from a plurality of chemical arrays; selecting sums of squares quantities based on the querying; and generating a metric based on the at least two sums of squares quantities.
