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 spreadsheet 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:
