a. Compute the tracking signal using the mean
absolute deviation and running sum of forecast errors.
(Negative values should be indicated by a minus sign. Round
your "Mean Absolute Deviation", "Tracking Signal" to 2 decimal
places and all other answers to the nearest whole
number.)

Homework Answers
a.We have,
Deviation=Actual -Forecast
Deviation in period 1=B3-C3=50
(Drag this cell formula for rest of the periods)
Running sum of forecast errors=RSFE of period 1=Deviation of period 1 =50
RSFE of period 2 =E3+D4=150
(Drag this cell formula for rest of the periods)
Absolute deviation =Absolute value of (deviation)
Sum of absolute deviation of period 1=absolute deviation of period 1=50
Sum of absolute deviation of period 2=G3+F4=150
(Drag this cell formula for rest of the periods)
MAD of period 1=Absolute deviation of period 1=50
MAD of period 2=SUM($F$3:F4)/A4=75
(Drag this cell formula for rest of the periods)
Tracking signal =RSFE/MAD
Tracking signal of period 1=E3/H3=1
(Drag this cell formula for rest of the periods)
