ABC company is trying to select a good forecast method. They selected two approaches called F$1$ and

F$2.$ The MAD of $F1$ is $4$ and that of $F2$ is $2.$ Which of the following is true?

F$1$ is more accurate than F$2.$

F$2$ is more accurate than F$1.$

Neither F$1$ nor F$2$ is good enough since MAD is not equal to zero.

Either F$1$ nor F$2$ is good enough since MAD is not equal to zero.

All of the above.
