Homework Answers
The problem deals with the concept of moving averages.
The moving averages are successive averages of data values for a series with a constant sample size and they overlap.
The number of periods for seasonal data in the moving average should be equal to the period of the seasonality because this will smooth out the seasonal component from the series.
The problem says that the sales data has quarterly sales that means there are four period of the seasonality factors.
Since the number of periods for seasonal data in the moving average should be equal to the period of the seasonality, the number of periods for moving average is 4.
Ans:Therefore, when the moving average method is used to estimate the seasonal factors with quarterly sales data, a 4-period moving average is used.
