How to find the absolute error when given only one value
To find the absolute error when given only one value, you can compare the given value to the true or expected value. The absolute error is the absolute value of the difference between the given value and the true value.
Here is the formula to calculate absolute error:
Absolute Error = |Given Value - True Value|
For example, if the given value is 20 and the true value is 15, the absolute error would be:
Absolute Error = |20 - 15| = 5
Therefore, the absolute error in this case is 5.
