DAVERAGE Function Excel

DAVERAGE function in Excel 2007:

Averages the data in an Excel worksheet column or field based on the criteria you specify. Let’s say a teacher has a database of her students in Excel and she wishes to find the average marks or grades her students have achieved in Math. Daverage is the function to use. Or, a researcher wishes to know which model of a TV is purchased by which age group. Also, the General Manager of a sales team would like to know what is the average sales of his team in a certain area.

Database is the range of cells that makes up the list or database. In our example in the video it is ‘A1:C11’. 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 like ‘Name’, ‘Gender’ and ‘Age’.
Field specifies which column is used in the daverage function. Enter the column label enclosed between double quotation marks, such as “Age” or “Male” or a number 2 or 3 (without quotation marks) 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 in which you specify a condition for the column. We have specified the criteria ‘Male’ and ‘>=30’ below the labels ‘Gender’ and ‘Age’ respectively.
Once you have the data in place, you copy and paste the headers in an appropriate position on your Excel worksheet. Try avoiding pasting the headers below your data in case you wish to add more data later on. Now under the pasted header, as shown in the Excel training video and mentioned above, you define the data from which you wish to calculate the average from a specific column and the criteria like , in our example, ‘=”Male” ‘ and ‘ “>=30” ‘ under the ‘Gender’ and ‘Age’ columns respectively. As you can see the average age of males greater than or equal to 30 works out to ’40’.
