STDEV.S

Definition

Estimates standard deviation based on a sample (ignores logical values and text in the sample).

The standard deviation is a measure of how widely values are dispersed from the average value (the mean).

Syntax

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

The STDEV.S function syntax has the following arguments:

• Number1     Required. The first number argument corresponding to a sample of a population. You can also use a single array or a reference to an array instead of arguments separated by commas.

• Number2, ...     Optional. Number arguments 2 to 254 corresponding to a sample of a population. You can also use a single array or a reference to an array instead of arguments separated by commas.

Remarks

• STDEV.S assumes that its arguments are a sample of the population. If your data represents the entire population, then compute the standard deviation using STDEV.P.

• The standard deviation is calculated using the "n-1" method.

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

• Logical values and text representations of numbers that you type directly into the list of arguments are counted.

• If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, text, or error values in the array or reference are ignored.

• Arguments that are error values or text that cannot be translated into numbers cause errors.

• If you want to include logical values and text representations of numbers in a reference as part of the calculation, use the STDEVA function.

• STDEV.S uses the following formula:

where x is the sample mean AVERAGE(number1,number2,…) and n is the sample size.

By adding the values you would like to calculate the STDEV.S formula for, Excellentable will generate the outcome:
