If 𝑎 a is the actual value and 𝑒 is the estimated value, what is the absolute error?

a−e

𝑎 / 𝑒

𝑒 − 𝑎

∣ 𝑎 − 𝑒 ∣

The absolute error is defined as the absolute difference between the actual value and the estimated value.

It is given by ∣a−e∣, where a is the actual value and e is the estimated value.
