Value: 35.00 points Forecasting Question #3 Two types of forecasting methods (F1 and F2) were used to calculate the predicted demand show below. PREDICTED DEMAND Period Demand 63 66 75 70 67 70 74 69 72 74 84 a. Calculate the Mean Absolute Deviation for F1 and F2. Which is more accurate? (Round your answers to 2 decimal places.) MAD F1 MAD F2 (Click to select appears to be more accurate b. Calculate the Mean Squared Error for F1 and F2. Which is more accurate? (Round your answers to 2 decimal places.) MSE F1 MSE F2 (Click to select) appears to be more accurate (Click to select) appears to be more accurate. c. You can choose which forecast is more accurate, by calculating these two error methods. When would you use MAD? When would you us MSE? Hint: Control charts are related to MSE; tracking signals are related to MAD. Either one might already be in use, familiar to users, and have past values for comparison. If (Click to select) 4 are used, MSE would be natural; if (Click to select) 4 are used, MAD would be more natura d. Calculate the Mean Absolute Percent Error for F1 and F2. Which is more accurate? (Round your Intermediate calculations to 2 decimal places and and final answers to 2 decimal places.) MAPE F1 MAPE F2 (Click to select) + appears to be more accurate.
