c. In general, since the annual pattern is quite seasonal, the moving average forecast is not a good one. It is difficult to say whether the January forecast is reliable. If there is an overall upward trend, then the $513 for next January may not be a bad forecast. However, forecasting February from the data is more risky. The three-month moving average (using November and December actuals and the January forecast) forecast would be $501. This is opposite of the previous year’s pattern in which February had higher sales than January.
