This came right out of the Access help
This example uses the Orders table to estimate the standard deviation of the
freight charges for orders shipped to the United Kingdom.
This example calls the EnumFields procedure, which you can find in the
SELECT statement example.
Sub StDevX()
Dim dbs As Database, rst As Recordset
' Modify this line to include the path to Northwind
' on your computer.
Set dbs = OpenDatabase("Northwind.mdb")
' Calculate the standard deviation of the freight
' charges for orders shipped to the United Kingdom.
Set rst = dbs.OpenRecordset("SELECT " _
& "StDev(Freight) " _
& "AS [Freight Deviation] FROM Orders " _
& "WHERE ShipCountry = 'UK';")
' Populate the Recordset.
rst.MoveLast
' Call EnumFields to print the contents of the
' Recordset. Pass the Recordset object and desired
' field width.
EnumFields rst, 15
Debug.Print
Set rst = dbs.OpenRecordset("SELECT " _
& "StDevP(Freight) " _
& "AS [Freight DevP] FROM Orders " _
& "WHERE ShipCountry = 'UK';")
' Populate the Recordset.
rst.MoveLast
' Call EnumFields to print the contents of the
' Recordset. Pass the Recordset object and desired
' field width.
EnumFields rst, 15
dbs.Close
End Sub

Does anyone know the expression for calculating standard
deviation? Thanks a lot in advance.
