VARPA

Calculates variance based on the entire population. In addition to numbers, text and logical values such as TRUE and FALSE are included in the calculation.

Syntax

VARPA(value1,value2, ...)

Value1,value2,...    are 1 to 30 value arguments corresponding to a population.

Remarks

• VARPA assumes that its arguments are the entire population. If your data represents a sample of the population, you must compute the variance using VARA.
• Arguments that contain TRUE evaluate as 1; arguments that contain text or FALSE evaluate as 0 (zero). If the calculation must not include text or logical values, use VARP instead.
• The equation for VARPA is :

  

Example

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