Three forecasting methods have been used to evaluate the same economic time series. The results are

Forecast from Method I	Forecast from Method 2	Forecast from Method 3	Realized Value of the Series
223	217	210	256
289	305	320	340
430	410	390	375
134	123	112	110
190	170	ISO	225
550	520	490	525

Compare the effectiveness of these methods by computing the MSE, the MAD, and the MAPE. Do each of the measures of forecasting accuracy indicate that the same forecasting technique is best? If not, why?
