=STDEVPA()
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).

◧ Arguments
| Argument | Type | Required | Description |
|---|---|---|---|
value1 |
Any type | Required | , value2, ... Value1 is required, subsequent values are optional. 1 to 255 values corresponding to a population. You can also use a single array or a reference to an array instead of arguments separated by commas. |

✦ Tips
- STDEVPA assumes that its arguments are the entire population. If your data represents a sample of the population, you must compute the standard deviation by using STDEVA.
- For large sample sizes, STDEVA and STDEVPA return approximately equal values.
- The standard deviation is calculated using the "n" method.
- Arguments can be the following: numbers; names, arrays, or references that contain numbers; text representations of numbers; or logical values, such as TRUE and FALSE, in a reference.
- Text representations of numbers that you type directly into the list of arguments are counted.
- Arguments that contain TRUE evaluate as 1; arguments that contain text or FALSE evaluate as 0 (zero).
- If an argument is an array or reference, only values in that array or reference are used. Empty cells and text values in the array or reference are ignored.
- Arguments that are error values or text that cannot be translated into numbers cause errors.
- If you do not want to include logical values and text representations of numbers in a reference as part of the calculation, use the STDEVP function.
- STDEVPA uses the following formula: where x is the sample mean AVERAGE(value1,value2,…) and n is the sample size.
