Elsa prepares a report on a regular basis that includes a summary of information about
the wages paid to student recruits. She lists the minimum hourly wage paid, the average

Using Aggregate Functions
You can calculate statistical information, such as totals and averages, on the records selected
by a query. To do this, you use the Access aggregate functions. Aggregate functions perform
arithmetic operations on selected records in a database. Figure 3-37 lists the most fre-
quently used aggregate functions. Aggregate functions operate on the records that meet a
query’s selection criteria. You specify an aggregate function for a specific field, and the
appropriate operation applies to that field’s values for the selected records.
