due to the relationship between the instrumentsignal, y, and the analyte concentration, x. The second is the random experimentalerror in the y-values, which is called the variation about regression. As we haveseen in Chapter 3, ANOVA is a powerful method for separating two sources of variationis such situations. In regression problems, the average of the y-values of the calibrationpoints, , is important in defining these sources of variation. Individual valuesof yi differ from for the two reasons given above. ANOVA is applied to separating thetwo sources of variation by using the relationship that the total sum of squares (SS)about is equal to the SS due to regression plus the SS about regression:
