DVAR(database, 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() calculates the estimates of the variance of a population, based on sample by using data in a specified column that matches the specified criteria.

Description

DVAR(database, 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

Name Age Salary Age
<40 >8000 >32
>30
Name Age Salary
John 34 5500
Bill 35 6500
Clark 29 7000
Bob 45 9000
Susan 37 4000
Jill 45 8000 


=DVAR(A4:C10,"Age",C1:C2)   : Calculates the estimated variance for 'Age' column in the range A4 to C10, for the cells with Salary>8000. Returns 41.952380952380956 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.
