This example references the following sheet information:

Customer Item  Quantity Ordered
1 Joe Shirt

10

2 Joe Hat 8
3 Sally Shirt 20

Given the table above, here are some examples of using AVERAGEIF in a sheet:

Formula Description Result
=AVERAGEIF(Customer:Customer, "Joe", [Quantity Ordered]:[Quantity Ordered]) Averages the values in the "Quantity Ordered" column, but only for the rows where the "Customer" is "Joe".  9
=AVERAGEIF(Item:Item, "Shirt", [Quantity Ordered]:[Quantity Ordered]) Averages the values in the "Quantity Ordered" column, but only for the rows where the "Item" is "Shirt".  15

If you need to add two criteria, for example the average quantity of shirts that Joe orders, use a combination of AVG and COLLECT. See the COLLECT Function for an example.
