DSTDEV(database, field, criteria)

where,

• $database$ is the range of cells that makes up the list or database
• $field$ shows which column is used in the function and
• $criteria$ is the range of cells that contains the specified criteria.

DSTDEV() calculates the standard deviation of a population, based on a sample by using data in a database column that matches the specified condition.

Description

DSTDEV(database, field, criteria)

• Standard deviation shows the variation of data points from the average value.
• If data points are close to mean value, a low standard deviation is observed. If data points are spread out from the mean value, a high standard deviation is observed.
• A $field$ argument can be expressed as "Salary" (a column name) or 3(position of the column).
• $criteria$ can be any range on the Calci with minimum of one column and at least one row indicating the condition.
• The $criteria$ columns should not overlap the list of data.

Bob	45	9000
Susan	37	4000
Jill	45	8000

=DSTDEV(A4:C10,"Age",B1:B3)   : Calculates the standard deviation for 'Age' column in the range A4 to C10, for the cells with 40>Age>30. 
 Returns 5.214829282387338 as a result.
=DSTDEV(A4:C10,3,D1:D2)   : Calculates the standard deviation for 'salary' in the range A4 to C10, for the cells with Age>32.
