DAVERAGE
Returns the average of values in a column of a Calc 'database' table, in rows which meet specified criteria.
Syntax:
DAVERAGE(database_table; field; criteria_table)
where
- database_table is a range defining the data to be processed.
- field is the column to examine. It may be a column number (1 is the first column of the database table, 2 is the second ...) or a column header (enclosed in quotation marks ””) or a cell referring to a column header.
- criteria_table is a range containing criteria, which are used to select which rows of the database_table to examine.
The Database functions overview fully describes the use of these parameters.
Example:
In this spreadsheet:
| A | B | C | D | E | |
| 1 | Name | Grade | Age | Distance to School | Weight |
| 2 | Andy | 3 | 9 | 150 | 40 |
| 3 | Betty | 4 | 10 | 1000 | 42 |
| 4 | Charles | 3 | 10 | 300 | 51 |
| 5 | Daniel | 5 | 11 | 1200 | 48 |
| 6 | Eva | 2 | 8 | 650 | 33 |
| 7 | Frank | 2 | 7 | 300 | 42 |
| 8 | Greta | 1 | 7 | 200 | 36 |
| 9 | Harry | 3 | 9 | 1200 | 44 |
| 10 | Irene | 2 | 8 | 1000 | 42 |
| 11 | |||||

| 13 | Name | Grade | Age | Distance to School | Weight |
| 14 | 2 |
DAVERAGE(A1:E10; "Distance to School"; A13:E14)
- returns the average distance to school that children in the second grade have to travel (650).
DAVERAGE(A1:E10; 4; A13:E14)
- returns the same result.
DAVERAGE(A1:E10; D1; A13:E14)
- also returns the same result.
Issues:
The OOo2.3 Help implies that 0 as a field will include the entire database table. This seems to be wrong - only the average of a single column can be found.
