KURT

Returns the kurtosis of a data set. Kurtosis characterizes the relative peakedness or flatness of a distribution compared with the normal distribution. Positive kurtosis indicates a relatively peaked distribution. Negative kurtosis indicates a relatively flat distribution.

Syntax

KURT(number1,number2, ...)

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

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 four data points, or if the standard deviation of the sample equals zero, KURT returns the #DIV/0! error value.
• Kurtosis is defined as:

  

  where:

  s is the sample standard deviation.
