1. Cost behavior is the most important characteristic for managerial decision making.
True False
2. In general, accounting records accumulate cost information according to its behavior (i.e., variable and fixed).
True False
3. In general, cost behavior results are likely to differ between the engineering method and the account analysis method.
True False
4. The engineering method of determining cost behavior is particularly useful for new activities or products.

7. The account analysis method is more subjective than other cost estimation methods because it relies heavily on the personal judgment and experience of accountants.
True False
8. In general, the account analysis method focuses on the underlying relationship between cost and activities from the previous period.
True False
9. The relevant range represents those activity levels for which valid cost relationships have been observed.
True False
10. A scattergraph is useful for identifying outliers/irrelevant data points.
True False
11. One disadvantage of the high-low method is the highest and lowest points may not be representative of normal operating activities.
True False
12. One advantage that regression techniques have over other cost estimation methods is it generates information that can be used to determine how well the estimated cost equation will predict future costs.
True False
13. Because outliers are extreme data points, they can be included in the regression analysis and not significantly affect the results.
True False
14. In general, the use of multiple independent variables increases the proportion of the variation in the dependent variable explained by the cost equation.
True False
15. One way to control the effects of a nonlinear relation between total costs and volume is to reduce the relevant range.
True False
16. The linear cost estimate tends to understate the slope of the cost line in ranges close to capacity.
True False
17. Cost estimates using regression analysis are always more accurate and dependable than cost estimates using the scattergraph methods.
True False
