It means the distance from zero. | 22 | (the absolute value of 22) is 22; | -22 | (the absolute value of -22) is also 22.
Basically just take out the negative, and that is the absolute value.

The absolute value of a number is a measure of how far it is from the origin (0). A distance is always positive so the absolute value of -22 is 22 (it is 22 units away from 0) and the absolute value of +22 is also 22.
There is a technical definition for absolute value, but you could easily never need it. You should view the absolute value of a number as its distance from zero. The absolute value of +3 is 3, since it is three away from zero. The absolute value of -3 is 3, since it is three away from zero the other way.
If you mean something like: | x | = -1 That has no solution. The absolute value of any expression on the inside of the absolute value bars can only be zero or positive.
The mean absolute deviation is 5
That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.That is called the "absolute value" of the number. For example:The absolute value of 5 is 5.The absolute value of -5 is also 5.
It means that the observations are all close to their mean value.
