STDEVPA function - The function of estimating standard deviations based on an entire population including both text and logical values ​​in Excel

The following article introduces you to the STDEVPA function - one of the functions in the statistical group is very popular in Excel.

STDEVPA function - The function of estimating standard deviations based on an entire population including both text and logical values ​​in Excel Picture 1

Description: The standard deviation estimation function is based on the whole population, including both text and logical values. Standard deviation is a measure of the dispersion of a value against the mean.

Syntax: STDEVPA (value1, [value2], .)

Inside:

- value1, [value2], .: are the values ​​you want to calculate the standard deviation, where value1 is the required parameter, the remaining parameters are optional and contain up to 254 value parameters .

Attention:

- The STDEV.S function assumes that its arguments are the entire population.

- For large sample sizes -> the functions STDEVA and STDEVPA return the same results.

- Standard deviation calculated using the method 'n'.

- Arguments can be numbers, names or arrays that contain numbers.

- The logical value with True is 1 default, false value is 0 default.

- If the argument is an array or a reference, only values ​​in that array are used.

- When the number is represented by a text style when typing directly into the argument list -> that value is still counted.

- Function error occurs when arguments are text or error values ​​cannot be converted.

- If you do not want to calculate both logical values ​​and text -> use the STDEVP function

- STDEVPA equation uses the formula:

[sqrt {frac {{sum {{{left ({x - overline x} right)} ^ 2}}}} {n}}]

Inside:

+ x is the sample mean AVERAGE (number1, number2, .)

+ n is the sample size.

For example:

Calculate the standard deviation based on the overall population of values ​​in the following data table:

- In the cell to calculate enter the formula : = STDEVPA (D6: D12)

- Press Enter -> standard deviation based on the whole of the above values ​​is:

Above are instructions and some specific examples when using the STDEVPA function in Excel.

Good luck!
