SKEW

Returns the skewness of a distribution. Skewness characterizes the degree of asymmetry of a distribution around its mean. Positive skewness indicates a distribution with an asymmetric tail extending toward more positive values. Negative skewness indicates a distribution with an asymmetric tail extending toward more negative values.

Syntax

SKEW(number1,number2, ...)

Number1,number2...   are 1 to 30 arguments for which you want to calculate skewness.

Remarks

• The arguments must be either numbers or column references that contain numbers.
• If a column reference argument contains text, logical values, or is empty , those values are ignored; however, arguments with the value zero are included.
• If there are fewer than three data points, or the sample standard deviation is zero, SKEW returns the #DIV/0! error value.
• The equation for skewness is defined as:
