Problem 3-21 Two different forecasting techniques (Fl and F2) were used to forecast demand for cases of bottled water. Actual demand and the two sets of forecasts are as follows: PREDICTED DER Period Demand a. Compute MAD for each set of forecasts. Given your results, which forecast appears to be more accurate? (Round your answers to 2 decimal place.) MAD F1 MAD F2 Click to select appears to be more accurate b. Compute the MSE for each set of forecasts. Given your results, which forecast appears to be more accurate? (Round your answers to 2 decimal places.) PISEF1 Click to select appears to be more accurate, c. In practice, either MAD or MSE would be employed to compute forecast errors. What factors might lead a manager to choose one rather than the other Either one might already be in use, familiar to users and have past values for comparison. If it are used. MSE would be naturat Cikolectare used, MAD would be more natural d. Comoute MAPE for each data set Which forecast appears to be more accurate? Round your intermediate calculations to 2 a. Compute MAD for each set of forecasts. Given your results, which forecast appears to be more accurate? (Round your answer decimal place.) MAD F1 MAD F2 (Click to select) appears to be more accurate. b. Compute the MSE for each set of forecasts. Given your results, which forecast appears to be more accurate?
