DVAR Function

The DVAR function is one of the database functions. It is used to estimate the variance of a population based on a sample by using the numbers in a field (column) of records in a list or database that match conditions that you specify.

The DVAR function syntax is:

DVAR(database, field, criteria)

where

database is the range of cells that make up a database. It must contain column headings in the first row.

field is an argument that specifies which field (i.e. column) should be used. It can be specified as a number of the necessary column, or the column heading enclosed in quotation marks.

criteria is the range of cells that contain conditions. It must contain at least one field name (column heading) and at least one cell below that specifies the condition to be applied to this field in the database. The criteria cell range should not overlap the database range.

To apply the DVAR function,

  1. select the cell where you wish to display the result,
  2. click the Insert function Insert function icon icon situated at the top toolbar,
