Assume a forecast of 61 for month 3: Month Actual Sales Forecast 3-Month Moving Average Forecast Exponential Smoothing 56 67 Before You Begin: To use a three-period moving average, remember that you ways have to compute the average of the latest three observa- ons. As new data become available, drop off the oldest data. the exponential smoothing part of this problem, before you in make sure that you have the three pieces of information u need: the current period's forecast (61 for month 3), the ent period's actual value (58), and a value for the smoothing current period's actual valu coefficient (a = 0.3).
