Answer #1
The formula used to calculate the mean absolute forecast error in percentage is :
Where, n is the number of terms, At is the actual value and Ft is the forecasted value.
Thus, calculating each term individually in the above formula, we get:
Thus, value of M = 1/6 * 0.04785817 = 0.0079764
Thus, the mean absolute forecast error for the Australian Dollar is 0.7976% (The second choice)
