Answer:
The Second Method
Step-by-step explanation:
APE (Absolute Percentage Error) = absolute difference / actual * 100
APE for First method = 61.93
APE for second method = 54.97
MAPE (Mean absolute Percentage error) = Sum of absolute Percentage error/ Number of observations. ( i.e., 4)
Then,
MAPE for the first method = 61.93 / 4 = 15.482
MAPE for the second method = 54.97 / 4 = 13.472
So, MAPE for second method is less than the MAPE for first method.
