Two different forecasting techniques were used to forecast demand for cases of bottled water in a store. Actual demand and the two sets of forecasts for seven periods are as follows: Forecast Demand Period 1 2 3 Demand 71 77 72 79 74 75 82 F1 72 74 75 76 4 F2 71 76 73 75 74 75 76 5 6 7. 78 79 a-1. Calculate the MAD for each set of forecasts. (Round the final answers to 2 decimal places.) F1 F2 A-2 Which technique annears to he more accurate? a-1. Calculate the MAD for each set of forecasts. (Round the final answers to 2 decimal places.) F1 F2 a-2. Which technique appears to be more accurate? (Click to select) b-1. Calculate the MSE for each set of forecasts. (Round the final answers to 2 decimal places.) F1 F2 b-2. Which technique appears to be more accurate? b-2 Which technique appears to be more accurate? (Click to select) c-1. Calculate the MAPE for each set of forecasts. (Round the final answers to 2 decimal places.) F1 3 F2 c-2 Which technique appears to be more accurate? (Click to select) d-1. Do all three of forecast errors provide the same conclusion (i.e., are they consistent) in this case? (Click to select) d-2. Do you expect consistent results in every case? (Click to select) (Click to select) will have lower MSE than (Click to select) v if obs 7 for F1 was 84. c-2 Which technique appears to be more accurate? (Click to select) d-1. Do all three of forecast errors provide the same conclusion (i.e., are they consistent) in this case? Click to select) d-2. Do you expect consistent results in every case? (Click to select) (Click to select) will have lower MSE than (Click to select) if obs 7 for F1 was 84. e. In practice, either MAD, MSE, or MAPE would be employed to compute a measure of forecast errors. What factors might lead manager to favour one?
