DAVERAGE

Averages the values in a column of a list or database that match conditions you specify.
Syntax
DAVERAGE(database,field,criteria)
Database    is the range of cells that makes up the list or database. A database is a list of related data in which rows of related information are records, and columns of data are fields. The first row of the list contains labels for each column.
Field    indicates which column is used in the function. Field can be given as text with the column label enclosed between double quotation marks, such as "Age" or "Yield," or as a number that represents the position of the column within the list: 1 for the first column, 2 for the second column, and so on.
Criteria    is the range of cells that contains the conditions you specify. You can use any range for the criteria argument, as long as it includes at least one column label and at least one cell below the column label for specifying a condition for the column.

Example
The example may be easier to understand if you copy it to a blank worksheet.

	A	B	C	D	E
1	Tree	Height	Age	Yield	Profit
2	Apple	>10
3	Pear
4	Tree	Height	Age	Yield	Profit
5	Apple	18	20	14	105.00
6	Pear	12	12	10	96.00
7	Cherry	13	14	9	105.00

AVERAGE

AVERAGE

Returns the average (arithmetic mean) of the arguments.
Syntax
AVERAGE(number1,number2,...)
Number1, number2, ...    are 1 to 30 numeric arguments for which you want the average.
Remarks

• The arguments must either be numbers or be names, arrays, or references that contain numbers.
• If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.

Tip

When averaging cells, keep in mind the difference between empty cells and those containing the value zero, especially if you have cleared the Zero values check box on the View tab (Options command, Tools menu). Empty cells are not counted, but zero values are.
