Answer: 12
Explanation:
Absolute Deviation = | Sales - Forecast|
Absolute Deviation for year 2010 = 17
Absolute Deviation for year 2011 = 7
Absolute Deviation for year 2012 = 9
Absolute Deviation for year 2013 = 20
Absolute Deviation for year 2014 = 7
MAD = Average of Absolute Deviation = Sum of Absolute Deviation/5 = 60/5 = 12
Add Answer to:

Assume you are analyzing a time series of 12 observations. Using a 3-period moving average, you successfully calculate the Mean Absolute Error (MAE), Mean Square Error (MSE), and Mean Absolute Percentage Error (MAPE) for each forecasted time period. You then sum the error calculations for each time period for each of the three error calculation techniques respectively. You end up with: MAE 53.5, MSE 547.25, and MAPE 44.15%. To complete your error calculation and compare the accuracy of the 3-period...
