This post will guide you how to use the STDEVP function with syntax and examples in Microsoft excel.

Description

The Excel STDEVP function returns the standard deviation of a population based on an entire population of numbers. This function has been replaced by the STDEV.P function in Excel 2010. The standard deviation is used to identify the amount that a set of values differ from the average value.

The STDEVP function is a build-in function in Microsoft Excel and it is categorized as a Statistical Function.

= STDEVP(number1,[number2],...)

Where the STDEVP function arguments are:

• number1-This is a required argument.  The first number or cell reference in a sample of a population.
• number2 – This is an optional argument.  Number arguments 2 to 255 corresponding to a sample of a population. and it can only accept up to 30 number arguments in Excel 2003 or older.

• The standard deviation is calculated using the “n” method.
• The STDEVP function is only used for its arguments are the entire population, and if the argument represents a sample of the population, you need to use the STDEVP function to calculate the standard deviation.
• If the argument contain the logical values and text representations of numbers and those values will be counted.
