The database argument is a range of cells that includes field headers, field is the name or index of the field to query, and criteria is a range of cells with headers that match those in database. Using the example above, you can get the standard deviation of heights for the group “Fox” with either of these formulas: The standard deviation for all heights in C8:C13 is calculated in F5 with the STDEV.S function:

### Criteria options

The criteria can include a variety of expressions, including some wildcards. The table below shows some examples: Note: Support for wildcards is not quite the same as with other functions like COUNTIFS, SUMIFS, MATCH, etc. For example, the pattern ??? will match strings with 3 exactly characters in more modern functions, but not in the database functions. If you are using wildcards, test carefully.

### Multi-row criteria

The criteria range for DSTDEV can include more than one row below the headers. When criteria includes more than one row, each row is joined with OR logic, and the expressions in a given criteria row are joined with AND logic. Notes:

DSTDEV is the mean to calculate variance for a sample. If data represents the entire population, use the DSTDEVP function. DSTDEV supports wildcards in criteria. Criteria can include more than one row (as explained above). The field argument can be supplied as a name in double quotes ("") or as a number representing field index. The database and criteria ranges must include matching headers.
