---

Value that does not change in testing, so that the effects of changes in the values of other elements can be studied. For example, when a control package is tested against a test package, one element, such as offer, copy or design, is changed and all other elements are held constant. Any difference in response to the control and test packages can be attributed to the element that changed.

Value that remains unchanged, for example, during the execution of a computer program. Literal expressions, such as 3.5 and George Washington are constants because they always stand for the same value.

Same as Mortgage Constant.
