Open this spreadsheet C. The worksheet labeled Original contains the data as it appears in the report. Scroll through the data in this worksheet and do a
spot check to verify that it is, in fact, the same table. This will give you some
practice in navigating the table.
Once you are comfortable navigating, click the Modified tab. In this worksheet
a few changes have been made to the table:
• Cells that contained H/ in the original table now contain zeros. H/
indicated that a particular carrier didn't have a hub at a particular
airport. In other words, it had arriving flights with 0% arriving on time.
. For each airport, an additional column labeled # ON TIME has been
added.
. On the far right, you will find a TOTAL area with three new columns: # OF
ARR., # ON TIME, and % ON TIME.
By filling in all of the blank columns, you'll transform the table into a two-way
table. Below you'll find instructions for filling in the blank columns to complete
the two-way table.
Before you start, make a copy of the Modified worksheet in case you make a
mistake. One way to do this is to right-click the Modified tab, select Move or
Copy on the shortcut menu, select the Create a copy checkbox, and click OK.
This procedure may vary slightly depending on your version of Microsoft Excel.
If you make a mistake, just delete the Modified tab you created by
right-clicking it and selecting Delete from the shortcut menu. Then make a
new copy of the Modified worksheet and start again.
To complete the # ON TIME column for each airport:
. Click in cells C8-C22 and look at the formula bar to get an understanding
of the formulas in these cells. Do the same with cell C23.
• Copy cells C8-C23, and paste them into the space for cells F8-F23.
• Verify that all the formulas are doing what you expect
• Repeat this procedure to fill in the # ON TIME column for each individual
airport
To complete the TOTAL area on the right:
• Go to columns CK and CL at the far right of the table. Examine what the
formulas do for rows 8-22. Now examine the formula in cells CK23 and
CL23
• Click in Cell CM8.
• Enter a formula in the formula bar that will calculate what percentage of
total arrivals are on-time arrivals.
• Once you're satisfied this formula works, copy it into all the cells in that
column (CM8-CM22, plus CM23).
Submit your worksheet to your teacher using the digital drop box. Note that
you will use this spreadsheet again in Task 4.
