5-16 Using MAD, determine whether the forecast in Problem 5-15 or the forecast in the section concerning Wallace Garden Supply is more accurate.
Forecast error = Actual value – Forecast Value MAD = ∑ |Forecast error |/ n

Problem 22 Consider the following forecast results. Caloulate MFE, MAD, and MAPE, using the data for the months January through June. Does the forecast model under- or overforecast? Actual Forecast Month Demand January February March 968 1,091 1,089 1,063 1,054 898 1,029 1,113 June 1,013 1.100 The MFE slag (Enter your response rounded to one decimal place and include The MAD is(Enter your response rounded to one decimal place,) a minus sign if necessary)
Use Solver to determine the alpha that minimizes the MAD for the exponential smoothing forecast for the data that appear in this table. Use the actual demand of period 1 as the forecast for period 2 and then use the forecasts for periods 2 through 9 to calculate MAD. Period Demand 1 272 2 278 3 269 4 280 5 267 6 258 7 278 8 298 9 286 10 290 0.43 0.36 0.54 0.62
