In database applications queries are commonly used to quickly get the average of a field in a database table. Queries are used to retrieve information from your table and can also do some heavy lifting such as data transformations or calculations. In a query you can use the "Avg" function to calculate the arithmetic mean of a set of values in a specific field.
