DVARP (Array,Field,Criteria)

Where $Array$ is the range of cells that makes up the list or database
$Field$ shows which column is used in the function and
is the range of cells that contains the specified criteria.
- DVARP(), calculates variance based on the entire population of selected database entries.

Description

DVARP (Array,Field,Criteria)

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

	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

=DVARP(A4:C10,"Age",C1:C3)   :  Calculates the true variance for Age column in the range A4 to C10, for the cells with Salary>8000. 
Returns 35.95918367346939 as a result.
=DVARP(A4:C10,3,B1:B3)   :  Calculates the true variance for Salary column in the range A4 to C10, for the cells with 40>Age>30. 
Returns 2506172.839506173 as a result.
