Compute MAD for each set of forecasts. Given your results, which forecast appears to be more accurate? (Round your answers to 2 decimal places.) MAD F1 MAD F2 O II F2 appears to be more accurate b.

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 control charts are used, MSE would be natural tracking signals unod d. Compute MAPE for each data set. Which forecast appears to be more accurate?
