STDEVP Function

Basic Description

The Excel STDEVP function calculates the standard deviation of a supplied set of values.

Syntax: STDEVP( number1, [number2], … )

where the arguments, number1, [number2], etc, are one or more numerical values, arrays of values, or references to cells containing values. If you are using Excel 2007 or a later version of Excel, you can enter up to 255 number arguments to the Stdevp function. However, in Excel 2003, the function can only accept up to 30 number arguments.

Note that the Stdevp function is used when calculating the standard deviation for an entire population. If you are calculating the standard deviation of an sample population, you need to use the Stdev function. Note also, that the Stdevp function ignores text values and logical values if these are supplied as part of an array. If you want a function that includes text and logical values in the calculation, consider using the Stdevpa function.

(Note that text representations of numbers, that are supplied as a part of an array, are not interpreted as numeric values by the Stdevp function)

#VALUE! Occurs if any values that are supplied directly to the Stdevp function are text values that cannot be interpreted as numeric values.
