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: For'e cast Demand Per'iod Demand F1 F2 1 7B 72 71 2 78 73 72 3 71 73 74 4 74 74 75 5 72 75 74 5 74 76 73 7 Be 77 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 appears to be more accurate? (Click to select)v 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? (Click to select) v c-1. Calculate the MAPE for each set of forecasts. (Round the final answers to 2 decimal places.) F1 F2 c-2. Which technique appears to be more accurate? (Click to select) v d-1. Do all three of forecast errors provide the same conclusion (i.e., are they consistent) in this case? (Click to select) v d-2. Do you expect consistent results in every case? (Click to select) v (Click to select) | will have lower MSE than (Click to select) if obs 7 for F1 was 82. e. In practice, either MAD, MSE, or MAPE would be employed to compute a measure of forecast errors. What factors might lead a manager to favour one?
