Returns the population variance for the data points in value_expression.

This function returns the REAL data type.

To invoke the time series version of this function, use the GROUP BY TIME clause. For more information, see Teradata Vantageā„¢ - Time Series Tables and Operations, B035-1208.


The variance of a population is a measure of dispersion from the mean of that population.

Do not use VAR_POP unless the data points you are processing are the complete population.


When the population has no non-null data points, VAR_POP returns NULL.

Division by zero results in NULL rather than an error.
