EXERCISE 5-12 (30 MINUTES)

2. As shown in the graph in part (2) of problem 5-17, the high and low points in this case fall in such a way they are not representative of all points of cost data. A regression line drawn through these two points would be too steep and thus result in an inaccurate cost formula. This is the major defect in the high-low method; although it is simple to apply, the manager must be careful in its use or misleading information may result.
