Answer 5

An absolute value is used when you only care about the magnitude of a number and you don't care whether the number is positive or negative.

For example there are times in statistics when your are dealing trying to find out if the average of a sample matches a particular bell curve. It may the the that sample average is to greater or less than the average of the bell curve. When you do your statistical analysis, you don't care which it is, just that the average is outside of a predetermined standard limit . You would use an absolute value as part of some rather complicated calculations.
