An analyst must decide between two different forecasting techniques for weekly sales of roller blades: a linear trend equation and the naive approach. The linear trendequation is Ft = 125 + 2.2t, and it was developed using data from periods 1 through 10. Based on data for periods 11 through 20 as shown in the table, which of thesetwo methods has the greater accuracy if MAD and MSE are used?

Forecasting techniques are very valuable in business planning, but without effectively examining the forecasting error, a business could make very flawed decisions. It is critical that we always evaluate the level of error and use this information to inform decisions about production, stocking, etc. For each of the error measures below, describe their strengths and weaknesses. Finally, select the method you believe would be most useful. forecast error CFE mean bias MAD MAPE
