Calculate kurtosis in excel



One of Excel statistical functions is the kurtosis function.This function can be used to calculate the kurtosis of a dataset. Kurtosis is a 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 for kurtosis

KURT(number1,number2,...)

With

Number1, number2, ... are 1 to 255 arguments for which you want to calculate kurtosis. You can also use a single array or a reference to an array instead of arguments separated by commas.

Notes :
a. Arguments can either be numbers or names, arrays, or references that contain numbers.
b. Logical values and text representations of numbers that you type directly into the list of arguments are counted.
c. If an array or reference argument contains text, logical values, or empty cells, those values are ignored; however, cells with the value zero are included.
d. Arguments that are error values or text that cannot be translated into numbers cause errors.
e. 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.

For examples :

1. Create table below
kurtosis
2. In cell C3 type formula:
=KURT(A3:A13)

This formula will calculate the kurtosis of data on range A3:A13
