Kurtosis Calculator

Calculate both kurtosis and relative kurtosis (excess kurtosis) to measure the relative weight of your distribution's tails. Identify if your data has more or fewer extreme values compared to a normal distribution.

How to Calculate Kurtosis

  1. Enter your numeric data directly into the data table or upload a CSV file
  2. Use the "Select Data Column" control to choose which column of data to analyze
  3. The calculator will automatically compute both kurtosis and relative kurtosis values
  4. View the distribution type classification and interpretation
  5. Examine the visualization to understand the tail weight of your data distribution
