DVAR (Array,Field,Criteria)


  • Where is the range of cells that makes up the list or database
  • shows which column is used in the function and
  • is the range of cells that contains the specified criteria.
    • DVAR(), estimates variance based on a sample from selected database entries.

Description

DVAR (Array,Field,Criteria)

  • A argument can be expressed as "Salary" (a column name) or 3(position of the column).
  • can be any range on the Calci with minimum of one column and at least one row indicating the condition.
  • The 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


=DVAR(A4:C10,"Age",C1:C3)   : Calculates the estimated variance for 'Age' column in the range A4 to C10, for the cells with Salary>8000. 
Returns 41.9524 as a result. =DVAR(A4:C10,3,B1:B3) : Calculates the estimated variance for 'salary' in the range A4 to C10, for the cells with 40>Age>30.
Returns 2819444.4444444445 as a result.
