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.
