Formula generator for DVAR function
The DVAR function is used to calculate the variance of a population sample selected from a database table-like array or range using a SQL-like query. It takes three arguments: 'database' represents the range or array containing the database table, 'field' specifies the column or range of columns to consider for the calculation, and 'criteria' defines the SQL-like query to filter the data before calculating the variance.

DVAR formula syntax
The DVAR function in Excel is used to calculate the variance of a dataset based on specified criteria. Its syntax is as follows: DVAR(database, field, criteria) - "database" refers to the range of cells that contains the dataset you want to analyze. - "field" specifies the column or range of cells within the database that you want to calculate the variance for. - "criteria" is an optional range of cells that defines the conditions or criteria that must be met for a data point to be included in the calculation. Note that the criteria must be specified in the same format as the database, with each column having a label in the first row. The DVAR function will return the variance of the dataset that meets the specified criteria.
Use Cases & Examples
In these use cases, we use the DVAR function to calculate the variance of values in a range. The DVAR function is particularly useful when you want to measure the variability or spread of a set of data points within a specified range.
