DSTDEV function: Description, Usage, Syntax, Examples and Explanation
What is DSTDEV function in Excel?
DSTDEV function is one of Database functions in Microsoft Excel that 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 of DSTDEV function
DSTDEV(database, field, criteria)
The DSTDEV function syntax has the following arguments:
- Database: 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: 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: 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.
DSTDEV formula explanation
- 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.
Example of DSTDEV function
Steps to follow:
1. Open a new Excel worksheet.
2. Copy data in the following table below and paste it in cell A1
Note: For formulas to show results, select them, press F2 key on your keyboard and then press Enter.
You can adjust the column widths to see all the data, if need be.
