Question: Compute the forecast errors for months 2 to 6 and then calculate the MAD and Mean Absolute Percentage Error (MAPE) for those months for each
Compute the forecast errors for months 2 to 6 and then calculate the MAD and Mean Absolute Percentage Error (MAPE) for those months for each of the two sets of forecasts. Which value seems to be more appropriate for this method?
| Month | Sales / Demand |
| 1 | 1443 |
| 2 | 1358 |
| 3 | 1342 |
| 4 | 1298 |
| 5 | 1277 |
| 6 | 1183 |
When =0.5, the MAD of forecast errors for months 2 to 6 is .
When =0.5, the MAPE of forecast errors for months 2 to 6 is %.
When =0.7, the MAD is and the MAPE is %.
