Calculates variance based on the entire population.

Syntax

VARP ( number1 ,number2, ...)

Number1,number2, ... are 1 to 30 number arguments corresponding to a population.

  • Logical values such as TRUE and FALSE and text are ignored. If logical values and text must not be ignored, use the VARPA function.

Remarks

  • VARP assumes that its arguments are the entire population. If your data represents a sample of the population, then compute the variance using VAR.

  • The equation for VARP is:
