# Absolute Error Definition

The **absolute value** is the **difference **between the **observed or measured value and the quantity's actual value**.It is an inadequate type of error because it does not provide any significant details about the error. For instance, while estimating the distances between the unknown distance between path A and B in kilometers; you maybe get the error of few centimeters that is insignificant and irrelevant. But suppose in another case, like assembling and measuring a machine where centimeters error is a significant error. In both cases, the errors are in the form of centimeters. However, the error in the second case is more critical than in the first case.

## Formula of Absolute Error

For a more precise understanding, let's check the formula for absolute error:

Absolute Error = inferred value - actual value

**Note:**

To know about absolute value, you can use our Absolute Value Definition.

### Example

For more prices understanding, let us have a look at the example listed below:

Suppose the quantity of actual value is 22.13, and inferred value is 23.09, then the value of absolute error will be:

**Given data**

actual value = 22.13

inferred value = 23.09

**To Find**

Absolute Error = ?

**Solution**

To get an absolute error, let's use the formula below:

Absolute Error = inferred value - actual value

Putting values in the formula:

Absolute Error = 23.09 - 22.13 = 0.96
