# STDEV.S Function

The STDEV.S function is one of the statistical functions. It is used to estimate standard deviation based on a sample (ignores logical values and text in the sample).

The STDEV.S function syntax is:

STDEV.S(number1 [, number2], ...)

where number-1(2) is up to 255 numeric values entered manually or included into the cells you make reference to.

Note: if a reference argument contains text, logical values, or empty cells, the function will ignore those values, but treat the cells with the zero values.

To apply the STDEV.S function,

1. select the cell where you wish to display the result,
2. click the Insert function icon situated at the top toolbar,
   or right-click within a selected cell and select the Insert Function option from the menu,
   or click the icon situated at the formula bar,
3. select the Statistical function group from the list,
4. click the STDEV.S function,
5. enter the required arguments separating them by commas or select a range of cells with the mouse,
6. press the Enter button.

The result will be displayed in the selected cell.
