VAR.P function - Function that calculates variance based on the entire set, ignoring logical values ​​and text in Excel

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

Description: The function performs calculation of variance based on the entire population, ignoring logical values ​​and text. Support functions from Excel 2010 onwards.

Syntax: VAR.P (number1, [number2], .)

Inside:

- number1, [number2], .): The arguments in the whole need to calculate the variance, where number1 is the required argument, the next arguments are optional and contain up to 254 number arguments .

Attention:

- The VAR.P function assumes that its arguments are whole.

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

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

- When typing logical values ​​and presenting numeric values ​​into function arguments -> these values ​​are still calculated.

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

- If you want to calculate both logical values ​​and text -> use VARPA function .

- The equation to calculate the VAR.P function is:

[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 variance based on the entire set of number values ​​in the following data table:

- In the cell to calculate enter the formula : = VAR.P (D6: D10)

- Press Enter -> variance based on the entire set of number values ​​is:

-Where the values ​​are text or logic -> the function ignores these values:

Above are instructions and some specific examples when using VAR.P function in Excel.

Good luck!
