The DSTDEV function is used to calculate the Standard Deviation based on a sample, by using the numbers in a column in a table/database that matches the conditions given. Note: Standard Deviation is a measure that shows how much variation of values exists from the average (mean).
Formula:
=DSTDEV(Database Range, Field Name, Criteria Range) Whereas DatabaseRange is the entire table/database (including the title), FieldName is the field whose variance has to be found and CriteriaRange is the name of the FieldName
