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.
Value1,value2, ... are 1 to 30 value arguments corresponding to a population.
- 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 the VARP worksheet function instead.
- The equation for VARPA is:
Using the data from the VARA example and assuming that only 10 tools are produced during the production run, VARPA measures the variance of breaking strengths for all the tools.
VARPA(A2:E3) equals 678.8
