Taco sales by month are shown in the table.
The manager is open to suggestions for forecasting models. Plot the data and discuss the efficacy of the moving average, weighted moving average, exponential smoothing, and trend as the relate to this data.

If seasonal relatives are calculated on odd months and even months, the even relative is a 1.033 and the odd relative is 0.967. Plotting both a trend line and one with this seasonal adjustment reveals this.
