The high-low method of deriving an estimated cost line uses all the data points available. O b. The most complex of the cost estimation methods is the high-low method. O c In approximating the cost function, the account analysis classifies costs based upon an industrial engineer's evaluation of production methods, and material, labor, and overhead requirements. d. Engineering approach approximates cost function by classifying each account as either vanable or fixed based on the analyst's knowledge of how the account behaves. e. The high-low method is used to derive an estimated line of cost behavior by graphically connecting the two cost amounts identified with the highest and lowest volume levels
