Question

Which of the following statements is FALSE?

Select one:

a. Long-term forecasts tend to be less accurate than the short-term forecasts.

b. The smaller the number of periods ("n") used in the simple moving average forecasting method leads to a more sensitive forecast.

c. The larger “alpha” value of a simple exponential smoothing leads to a “more responsive” forecast.

d. Forecasts of suppliers tend to be less accurate than the forecasts of retailers in a supply chain.

e. Forecasts of individual products tend to be less accurate than the forecasts of product families.

Answer #1

**Answer: Option d**

**Rationale: The accuracy of the forecasts of suppliers
and retailers would depend on the methods they use but cannot be
conclusively said that one is better than the other.**

Options a, b, c, and e are true

- a is true because the long term forecasts have a higher deviation of error
- b is true because in simple moving average a responsive forecast depends on the number of periods
- c is true because a lower alpha value does not create a responsive forecast
- e is true because the error in individual products cancels the other errors resulting in less accuracy.

In Excel, create forecasts for periods 6-13 using each of the
following methods: 5 period simple moving average; 4 period
weighted moving average (0.63, 0.26, 0.08, 0.03); exponential
smoothing (alpha = 0.23 and the forecast for period 5 = 53); linear
regression with the equation based on all 12 periods; and quadratic
regression with the equation based on all 12
periods. Round all numerical answers to two
decimal places.
The actual values for 12 periods (shown in order) are:
