This example uses Excel's Grouping dialog box to create the groups automatically. If
you don't want to group in equal-sized bins, you can create your own groups. For ex-
ample, you may want to assign letter grades based on the test score. Select the rows
for the first group and then choose Group from the shortcut menu. Repeat these steps
for each additional group. Then replace the default group names with more meaningful
names.
Creating a Calculated Field or Calculated Item
Perhaps the most confusing aspect of pivot tables is calculated fields versus calculated items. Many pivot table
users simply avoid dealing with calculated fields and items. However, these features can be useful, and they
really aren't that complicated after you understand how they work.
First, some basic definitions:
Calculated field: A calculated field is a new field created from other fields in the pivot table. If your pivot
table source is a worksheet table, an alternative to using a calculated field is to add a new column to the
table and then create a formula to perform the desired calculation. A calculated field must reside in the Val-
ues area of the pivot table. You can't use a calculated field in the Columns area, Rows area, or Filter area.
Calculated item: A calculated item uses the contents of other items within a field of the pivot table. If your
pivot table source is a worksheet table, an alternative to using a calculated item is to insert one or more rows
and write formulas that use values in other rows. A calculated item must reside in the Columns area, Rows
area, or Filter area of a pivot table. You can't use a calculated item in the Values area.
The formulas used to create calculated fields and calculated items aren't standard Excel formulas. In other
words, you don't enter the formulas into cells. Rather, you enter these formulas in a dialog box, and they're
stored along with the pivot table data.
The examples in this section use the worksheet table shown in Figure 18-32. The table consists of five fields
and 48 rows. Each row describes monthly sales information for a particular sales representative. For example,
Amy is a sales rep for the North region, and she sold 239 units in January for total sales of $23,040.
