The least-squares regression method is:

A) A graphical method to identify cost behavior.
B) An algebraic method to identify cost behavior.
C) A statistical method to identify cost behavior.
D) The only identify cost estimation method allowed by GAAP.
E) A cost estimation method that only uses the two extreme values.

Least-Squares Regression Method

A statistical method used to estimate the relationship between variables by minimizing the differences between the observed values and the values predicted by a linear function.

Cost Behavior

The way in which costs change in relation to changes in a firm’s level of activity or volume of production.
