The Excel VARPA function computes the variance of for a population of data. Unlike the VARP function, the VARPA function evaluates text values and logicals in references.
Get variation of a population
=VARPA (number1, [number2], ...)
number1 - First number or reference.
number2 - [optional] Second number or reference.
The VARPA function calculates the variance for data that represents an entire population. Variance provides a general idea of the spread of data. Like the VARA function, the VARA function evaluates text values and logicals in references. Text is evaluated as zero, TRUE is evaluated as 1, and FALSE is evaluated as zero.
The Excel VAR function estimates the variance of a sample of data. If data represents the entire population, use the VARP function or the newer VAR.P function. VAR ignores text values and logicals in references.
