Figure 2-4: Rolling Averages Calculated Using V-VOL Frequency
Example rolling-average procedure using Microsoft Excel:
a. In cell C4, type =Average(b2:b7).
b. Press Enter.
This instructs the tool to calculate the average value in cells
B2 through B7 and populates C4 with that data.
c. Copy the value in C4.
d. Highlight cells C5 to the last C cell in the last row of workload
data in the spreadsheet.
e. Right-click the highlighted cells and select the paste option.
Excel maintains the logic and increments the formula values
initially entered in C4. It then calculates all the point in time
averages and populates the C cells.
