EXCEL DSTDEV FUNCTION

The Excel Dstdev function computes the sample standard deviation of a field (column) in a database for only a subset of the entries. A collection of one or more user-specified criteria defines the records to be included in the computation.

Syntax :

=DSTDEV(database, field, criterion)

Parameters :

  •  The following arguments:

Database :

  • A set of cells that contains the database. The field names should be specified in the database’s top row.

Field :

  • The database field (column) for which the sample standard deviation is to be determined. The can be either a field number or the field name (i.e. the header in the top row of the database) surrounded by quotations (e.g. “Subject”, “Name”, etc).

Criterion :

  • A range of cells containing the criteria for determining which records should be included in the computation. The range can include one or more criteria, which are given in one cell as a field name and the condition for that field in the cell below.

E.g. :

AgeName
>8Amy

Step By Step Guide of DSTDEV Function

Example :

The Dstdev function is used in the following example to calculate the sample standard deviation of English scores earned by male students. Cells G1 – H2 specify the conditions, while cell G3 displays the Dstdev formula. The Dstdev function above computes the sample standard deviation of the values in cells E6, E9, and E12, and so gives 10.4 percent.
