Objectives

Gain proficiency in using relative and absolute references

Explain the importance of isolating the assumptions in a worksheet

Use the fill handle to copy a range of cells Use pointing to enter a formula


Objectives (continued)

Insert a hyperlink into an Excel worksheet Save a worksheet as a Web page and then

view the page in a Web browser Import data from a web query into a

workbook; refresh the query to obtain current information

Describe the Today() function and its use in date arithmetic


Building a Worksheet

Take a few minutes and type in the next worksheet or copy Chapter 2 Practice 1-Alternative Payroll.xls


Building a Worksheet


Cell Referencing

Absolute reference: remains constant throughout a copy operation Specified with a dollar sign before the column

and row, i.e. $B$4

Relative reference: adjusts during a copy operation Specified without dollar signs, i.e. B4


Absolute and Relative Cell References

Use relative cell references for each employees gross pay

Use absolute cell references for withholding rate and FICA rate


Example of Isolated Assumptions

Assumptions are isolated and clearly labeled


Isolate Assumptions

Base your formulas on cell references, not values

The cells containing the values (assumptions) should be clearly labeled and set apart

Change the assumptions in the worksheet and see the effects instantly Also minimizes the chance for error: you change

the assumptions in one place


Isolate Assumptions

It is very common to use absolute references to refer to assumptions, since they normally remain the same for each row in the table. For values that change in each row, in this case, an employee’s gross pay, use relative references.

Notice that assumptions are clearly labeled and isolated from the body of the worksheet. This makes editing the values at a later date much easier.


Using Excel Effectively

Enter cell addresses in formulas and functions by pointing – watch out Excel is very sensitive Use the mouse to select the cell(s) More accurate than typing cell references

Enter Formulas in the formula box besides Fx Use the fill handle to copy

Select the cell(s) and drag to copy to a destination range

Insert comments


Using Excel Effectively

When copying a formula and using the fill handle, pay particular attention to the shape of the cursor. It must be a crosshair to use the fill handle to copy cells. You must release the mouse to copy the cells.

Also, the fill handle can only be used to copy to contiguous cells.

Comments can be used to explain why certain values were chosen and the logic behind formulas, the creator of the workbook.


PointingUse the mouse to select the cells to be included in the formula

Notice the color coding between the borders around the selected cells and the formula in the formula bar


Using the Fill Handle

Select cells E2:H2. Dragging the fill handle will copy all four cells to lower rows.

Border around selected area. Release the mouse and formulas are copied


Inserting Comments

Comments provide explanation for values and/or descriptions of formulas
