Skewness Calculator
How It Works
Input a list of numbers (comma-separated or space-separated) as the dataset. The calculator will compute the skewness, a measure of the asymmetry of the distribution, using the sample skewness formula. Click “Calculate” to see the result. Share or embed the calculator using the provided buttons.

About Skewness Calculator
The Skewness Calculator measures the asymmetry of a dataset’s distribution. A positive skewness indicates a right-skewed distribution, a negative skewness indicates a left-skewed distribution, and a skewness near zero suggests symmetry.
How to Use
- Enter a list of numbers, separated by commas or spaces (e.g., 1, 2, 3 or 1 2 3).
- Click “Calculate” to compute the skewness. The page will scroll to the result.
- Click “Clear” to reset the input and results.
- Click “Share” to copy the calculator’s URL to your clipboard.
- Click “Embed” to copy an iframe code for embedding on another website.
- The result and calculation steps will be displayed.
Formula
g_1 = \frac{n}{(n-1)(n-2)} \sum \left(\frac{x_i – \bar{x}}{s}\right)^3
Where:
- g_1 = sample skewness
- n = number of data points
- x_i = each data point
- \bar{x} = mean of the dataset
- s = sample standard deviation
Important Notes
- Enter at least three numbers in the dataset for a valid skewness calculation.
- Numbers can be integers or decimals, separated by commas or spaces.
- The keypad’s Clear button clears the input field.
- “Share” and “Embed” buttons require a browser that supports the Clipboard API.
