The use of Excel for forecasting
You are then required to produce a spreadsheet which forecasts the consumer expenditure on the product or service for the next quarter (or next 4 quarters in the case of decomposition) using each of the following three methods:
a) A four-period moving average.
b) Exponential smoothing with an optimal parameter determined by the Excel Solver.
c) Decomposition with a trend line and seasonality.
In each case, calculate the MAPE for the forecast method. Then submit your complete Excel spreadsheet to student central. There is no written report, but in the Student central comments box enter the name of the forecasting technique that you believe produced the best forecast and (in one sentence) explain your choice.
