3

Generate

Click Generate to create random numbers following a bell curve.

Frequently Asked Questions

What is a Gaussian/normal distribution?
A bell-shaped probability distribution where values near the mean are more likely. Used extensively in statistics, science, and machine learning.
What does standard deviation control?
Standard deviation controls the spread. A larger value means numbers are spread wider from the mean; smaller means more concentrated.
How accurate is this generator?
It uses the Box-Muller transform, a mathematically proven method to generate normally distributed random numbers.
Can I generate negative numbers?
Yes! With a Gaussian distribution, values can fall on either side of the mean, including negative numbers.
Is this tool free and private?
Yes, completely free. All generation happens in your browser - no data is sent anywhere.
