Note. , , and represent the various factor values (levels) ranging from small (low) to large (high); j represents various factors, Rj represents the range of the data, and T stands for the sum of the data. For example, represents the sum of the values of the test parameters corresponding to level “1” of the influence factors in the column “j”.
