1. Description and syntax used

This is a function that returns a standard deviation based on a sample, ignoring logical values ​​and text. Standard deviation is a measure of the dispersion of values ​​against the mean.

Syntax:

STDEV.S (number1,[number2], …)

Inside:

Number1,[Number2], …: These are the values ​​that you want to calculate the standard deviation, where Number1 is a required parameter, the remaining parameters are optional and contain a maximum of 254 number parameters.

Attention:

– Function STDEV.S Assuming its arguments are population patterns.

– Standard deviation calculated using the “n -1” method.

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

– When typing logical values ​​directly and presenting numerical 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 -> you use the function STDEVPA.

– Equation STDEV.S use the formula:

Inside:

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

+ n is the sample size.

2. Examples of specific situations

Suppose you need to calculate the standard deviation based on a sample of the values ​​in the following data table:

Step 1: In the cell to calculate -> you enter the formula: = STDEV.S (B3: B8)
