This function estimates the standard deviation of a population based on a sample by using the numbers in a column of a list or database that match the specified conditions.
DSTDEV( database, field, criteria )
Range of cells that make up the database; cell range reference
Column in the database, referred to by label or index
Range of cells that specify which rows in the database are used; cell range reference
The database argument is a range of cells that make up the database. Each column represents a field. The first row represents the field labels. Each remaining row represents a record of data.
The field argument determines which column in the database to use. The field argument can be a string (field label) or a number (field index).
The criteria argument is a range of cells that specify which rows in the database contain the conditions that select a subset of the data in the database. The first row represents field labels. The remaining rows represent conditions. Conditions in the same row are combined using an AND operation. Conditions in different rows are combined using an OR operation. Each condition can be a number or a string. The string can include a comparison operator (=, <>, <, >, <=, >=). If no operator is included then the equal operator (=) is assumed.
Wild card characters are not supported in the criteria argument.
This is one of several databases or list functions that treat a range of cells as if they were a database.
Accepts cell ranges for database and criteria. Accepts a string or a number for the field. Returns numeric data.
