STDEVPA

See Also

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. You can also use a single array or a reference to an array instead of arguments separated by commas.

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:

  

Example

The example may be easier to understand if you copy it to a blank spreadsheet.
