Which of the following is true of the exponential smoothing coefficient?
 a. It is a randomly generated value between 1 and +1.
  b. It is small for a time series that has relatively little random variability.
  c. It is chosen as the value that minimizes a selected measure of forecast accuracy such as the mean squared error.
  d. It is computed in relation with the order value, k, for the moving averages.

Question 2

We create multiple dashboards
 a. to help the user scroll vertically and horizontally to see the entire dashboard.
  b. so that each dashboard can be viewed on a single screen.
  c. to make sure the KPIs are not displayed in the data dashboard.
  d. so that all dashboards can be viewed on a single screen.

Answer to Question 1

c
RATIONALE: The criterion we will use to determine a desirable value for the smoothing constant  is the same as that proposed for determining the order or number of periods of data to include in the moving averages calculation; that is, we choose the value of  that minimizes the MSE.

Answer to Question 2

b
RATIONALE: Rather than requiring the user to scroll vertically and horizontally to see the entire dashboard, it is better to create multiple dashboards so that each dashboard can be viewed on a single screen.
