## Excel STDEVP Function

### Description

The Excel STDEVP function returns standard deviation based on the entire population. It can be used to measure how widely values are dispersed from the mean value. STDEVP function has been replaced with STDEV.P function, which has the same behavior.

### Syntax and arguments

Formula syntax

STDEVP(value1, [value2], ...)

Arguments

 Value1: Required, a number, a reference to a population. Value2, ...: Optional, the second number or reference that is up to 255 corresponding to a population.

### Return Value

The STDEVP function returns a numeric value.

### Remark

1. STDEVP function has been replaced with one or more new functions that may provide improved accuracy. Although it is still available now, you should better use the new function from now, avoiding it is not available in future Excel versions.

2. STDEVP function’s arguments are the entire population, if the data represents a sample of population, STDEV.S function may be rather appropriate.

3. STDEVP function using the “n” method to calculate.

4. Arguments can either be numbers or names, arrays or references that contain numbers.

5. Logical values and text representations of numbers that are directly typed into the list of arguments are counted.

6. If arguments are arrays or references, only numeric values are counted in the function, while empty cells and texts of error values are ignored.

Example: Basic Usage

There is a column B4:B8 containing a population of data. To get the standard deviation, please use formula as below:

=STDEVP(B4:B8)

=STDEVP({10,22,30,41,37})

Press Enter key to get the standard deviation.
