Calculates standard deviation based on the entire population given as arguments, including text and logical values. The standard deviation is a measure of how widely values are dispersed from the average value (the mean).
Syntax
STDEVPA(value1,value2,...)
Value1,value2,... are 1 to 30 values corresponding to a population.
Remarks
- STDEVPA assumes that its arguments are the entire population. If your data represents a sample of the population, you must compute the standard deviation using STDEVA.
- 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 STDEVP function instead.
- For large sample sizes, STDEVA and STDEVPA return approximately equal values.
- The standard deviation is calculated using the "biased" or "n" method.
- STDEVPA uses the following formula:
