Question

what is the formula of mean absolute error?

Answer 1

The formula for the absolute error (Δx) is:

(Δx) = xi – x,
Where: xi is the measurement,x is the true value.

Answer 2

The Mean Absolute Error is given by: The arithmetic mean of the positive magnitudes of all the absolute errors is called mean absolute error
∆ā=(|∆a1|+|∆a2|+|∆a3|+...+|∆an|)/n
