DSTDEVP(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.

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

Description

DSTDEVP(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.

Examples

Consider the following table with Employee details as input to DSTDEVP function.

	A	B	C	D
1	Name	Age	Salary	Age
2		<40	>8000	>32
3		>30
4	Name	Age	Salary
5	John	34	5500
6	Bill	35	6500
7	Clark	29	7000
8	Bob	45	9000
9	Susan	37	4000
10	Jill	45	8000

=DSTDEVP(A4:C10,"Age",B1:B3) : Calculates the true standard deviation for 'Age' column 
in the range A4 to C10, for the cells with 40>Age>30. 
Returns 4.916588197741686 as a result.
=DSTDEVP(A4:C10,3,D1:D2) : Calculates the true standard deviation for 'salary' 
in the range A4 to C10, for the cells with Age>32. 
Returns 1772.004514666935 as a result.
