Varp function

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.

St1	St2	St3	St4	St5	St6	St7	St8	St9	St10	Formula	Description (Result)
1345	1301	1368	1322	1310	1370	1318	1350	1303	1299	=VARP([St1], [St2], [St3], [St4], [St5], [St6], [St7], [St8], [St9], [St10])	Variance of breaking strengths for all the tools, assuming that only 10 tools are produced (678.84)
