How To Calculate Kurtosis In Excel

Introduction

Understanding the kurtosis of a dataset can provide valuable insights into its distribution, particularly the presence of outliers and the 'tailedness' of the data. Calculating kurtosis in Excel requires using complex statistical functions and can be time-consuming.

While this guide will show you the Excel method, you can skip the tedious manual calculations by using Sourcetable, an AI-powered spreadsheet that lets you calculate kurtosis and perform any other analysis just by asking its chatbot - try it now at https://app.sourcetable.com/.

Calculate Kurtosis in Excel

Using the KURT Function

Excel's KURT function computes kurtosis for a dataset, indicating its peakedness or flatness compared to a normal distribution. Positive kurtosis values denote a sharper peak, while negative values suggest a flatter shape. The function handles up to 255 inputs, which can be numerical values, names, arrays, or cell references.

Steps for Calculation

To calculate kurtosis in Excel, input your dataset into a column or row. Click on an empty cell where you want the kurtosis value to appear. Type =KURT() and select the range containing your data inside the parentheses. Press Enter to view the result.

Interpreting Kurtosis Values

A kurtosis value greater than zero implies a distribution with a sharper peak than a normal distribution. Conversely, a value less than zero indicates a flatter distribution. The magnitude of the kurtosis value reflects the degree of peakedness or flatness.

Calculating Excess Kurtosis

To find excess kurtosis, which is the kurtosis relative to a normal distribution, subtract 3 from the kurtosis value obtained. A positive excess kurtosis indicates a distribution with more pronounced tails, while a negative value suggests fewer extreme values than a normal distribution.
