This article describes the formula syntax and usage of the DSTDEV function (function: A prewritten formula that takes a value or values, performs an operation, and returns a value or values. Use functions to simplify and shorten formulas on a worksheet, especially those that perform lengthy or complex calculations.) in Microsoft Excel.
Description
Estimates the standard deviation 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.
Syntax
DSTDEV(database, field, criteria)
The DSTDEV function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):
 Database Required. The range of cells that makes up the list or database. A database is a list of related data in which rows of related information are records, and columns of data are fields. The first row of the list contains labels for each column.
 Field Required. Indicates which column is used in the function. Enter the column label enclosed between double quotation marks, such as "Age" or "Yield," or a number (without quotation marks) that represents the position of the column within the list: 1 for the first column, 2 for the second column, and so on.
 Criteria Required. The range of cells that contains the conditions that you specify. You can use any range for the criteria argument, as long as it includes at least one column label and at least one cell below the column label in which you specify a condition for the column.
Click here for criteria examples.
Remarks
 You can use any range for the criteria argument, as long as it includes at least one column label and at least one cell below the column label for specifying the condition.
For example, if the range G1:G2 contains the column label Income in G1 and the amount $10,000 in G2, you could define the range as MatchIncome and use that name as the criteria argument in the database functions.
 Although the criteria range can be located anywhere on the worksheet, do not place the criteria range below the list. If you add more information to the list, the new information is added to the first row below the list. If the row below the list is not blank, Microsoft Excel cannot add the new information.
 Make sure that the criteria range does not overlap the list.
 To perform an operation on an entire column in a database, enter a blank line below the column labels in the criteria range.
Examples
The example may be easier to understand if you copy it to a blank worksheet.

The estimated standard deviation in the yield of apple and pear trees if the data in the database is only a sample of the total orchard population. (2.97) 





Criteria examples
Important
 Because the equal sign is used to indicate a formula when you type text or a value in a cell, Microsoft Excel evaluates what you type; however, this may cause unexpected filter results. To indicate an equality comparison operator for either text or a value, type the criteria as a string expression in the appropriate cell in the criteria range:
=''=entry''
Where entry is the text or value you want to find. For example:
What you type in the cell 
What Excel evaluates and displays 
="=Davolio" 
=Davolio 
="=3000" 
=3000 
The following sections provide examples of complex criteria.
Multiple criteria in one column
Boolean logic: (Salesperson = "Davolio" OR Salesperson = "Buchanan")
To find rows that meet multiple criteria for one column, type the criteria directly below each other in separate rows of the criteria range.
In the following data range (A6:C10), the criteria range (B1:B3) displays the rows that contain either "Davolio" or "Buchanan" in the Salesperson column (A8:C10).

Multiple sets of criteria where each set includes criteria for multiple columns
Boolean logic: ( (Salesperson = "Davolio" AND Sales >3000) OR (Salesperson = "Buchanan" AND Sales > 1500) )
To find rows that meet multiple sets of criteria, where each set includes criteria for multiple columns, type each set of criteria in separate rows.
In the following data range (A6:C10), the criteria range (B1:C3) displays the rows that contain both "Davolio" in the Salesperson column and a value greater than $3,000 in the Sales column, or displays the rows that contain "Buchanan" in the Salesperson and a value greater than $1,500 in the Sales column (A9:C10).

Criteria to find text values that share some characters but not others
To find text values that share some characters but not others, do one or more of the following:
 Type one or more characters without an equal sign (=) to find rows with a text value in a column that begin with those characters. For example, if you type the text Dav as a criterion, Excel finds "Davolio," "David," and "Davis."
 Use a wildcard character.
The following wildcard characters can be used as comparison criteria.
Use 
To find 
? (question mark) 
Any single character For example, sm?th finds "smith" and "smyth" 
* (asterisk) 
Any number of characters For example, *east finds "Northeast" and "Southeast" 
~ (tilde) followed by ?, *, or ~ 
A question mark, asterisk, or tilde For example, fy91~? finds "fy91?" 
In the following data range (A6:C10), the criteria range (A1:B3) displays rows with "Me" as the first characters in the Type column or rows with the second character equal to "u" in the Salesperson column (A7:C9).

Criteria created as the result of a formula
You can use a calculated value that is the result of a formula (formula: A sequence of values, cell references, names, functions, or operators in a cell that together produce a new value. A formula always begins with an equal sign (=).) as your criterion. Remember the following important points:
 The formula must evaluate to TRUE or FALSE.
 Because you are using a formula, enter the formula as you normally would, and do not type the expression in the following way:
=''=entry''
 Do not use a column label for criteria labels; either keep the criteria labels blank or use a label that is not a column label in the range (in the examples below, Calculated Average and Exact Match).
If you use a column label in the formula instead of a relative cell reference or a range name, Excel displays an error value such as #NAME? or #VALUE! in the cell that contains the criterion. You can ignore this error because it does not affect how the range is filtered.
The following subsections provide specific examples of criteria created as the result of a formula.
Filtering for values greater than the average of all values in the data range
In the following data range (A6:D10), the criteria range (D1:D2) displays rows that have a value in the Sales column greater than the average of all the Sales values (C7:C10). In the formula, "C7" refers to the filtered column (C) of the first row of the data range (7).

Filtering for text by using a casesensitive search
In the data range (A6:D10), the criteria range (D1:D2) displays rows that contain "Produce" in the Type column by using the EXACT function to perform a casesensitive search (A10:C10). In the formula, "A7" refers to the filtered column (A) of the first row of the data range (7).
