Answer:
c. 20
Explanation:
Calculation to determine Which of the following is the resulting MAD value that can be computed from this data
Using this formula
MAD= [ABS( Year 1 actual unit demand - Forecast) + ABS (Year 2 actual unit demand - Forecast) + ABS (Year 3 actual unit demand - Forecast) + ABS (Year 4 actual unit demand - Forecast)]/ Number of years
Let plug in the formula
MAD = [ABS(100 - 120) + ABS (105 - 120) + ABS (135 - 120) + ABS (150 - 120)]/4
MAD =(ABS 20) + (ABS 15) + (ABS 15) + (ABS 30)/4
MAD= 80/4
MAD=20
Therefore the resulting MAD value that can be computed from this data is 20
