The mean absolute error is one of a number of ways of comparing forecasts with their eventual outcomes. In contrast with the classical MAPE (usually defined as "regular"), which ranges between $0$ and $\infty$, the symmetric MAPE expressed in percentage ranges between $0$ and $200\%$. First, calculate the difference of the measurement results by subtracting the reference laboratory's result from the participating laboratory's result.

When trying to model target variations, the constant output model is probably the most useful reference. If you take the half of this measure (which corresponds to the same formula above, but without the division by $2$ in the denominator) and express it as a decimal number, you get a simple and reliable measure of error that ranges between $0$ and $1$, with $0$ meaning perfect agreement and $1$ maximal (theoretical) disagreement.
