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:
Example
Suppose all 10 tools stamped from the same machine during a production run are collected and measured for breaking strength.
