The function SKEW returns the skewness of a given distribution. The skewness is nothing but the degree of asymmetry of a distribution around its mean.

If the function returns a positive value, it indicates that the distribution has an asymmetrical tail extending toward positive values and if it returns a negative value, it indicates that the given di8stribution has an asymmetrical tail extending toward negative values.

**Syntax**

The SKEW function has the following syntax and arguments

**=SKEW(number1, [ number2], —)**

Where

**‘number1, number2, —** number1 is a required argument and the further numbers are optional. 1 to 255 numbers for which you wish to find the skewness. You can use a reference to an array or a single array instead of numbers separated by commas.

**Constraints**

If there are less than three data points and if the standard deviation of the data points is zero, the function returns the #DIV/0! Error.

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

The equation for calculating the skewness is defined as

**Example**

The examples of the SKEW function are shown in the figure given below

So, this is how you can find the skewness of a distribution using the SKEW function that is present in Excel 2010 Application.
