Here is another sample to explain relationships between SQL Server statistic functions:

USE AdventureWorks;
GO
SELECT STDEVP(Bonus) ‘Standard Deviation for the Population’,
STDEV(Bonus) ‘Standard Deviation’,
VAR(Bonus) ‘Variance’,
STDEV(Bonus)* STDEV(Bonus) ‘VAR via STDEV’,
VARP(Bonus) ‘Variance for the Population’,
STDEVP(Bonus)* STDEVP(Bonus) ‘VARP via STDEVP’,
VAR(Bonus)*(COUNT(Bonus)-1)/COUNT(Bonus) ‘VARP via VAR ‘
FROM Sales.SalesPerson;
GO
Thanks
Oleg
