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) |
