Buyer's guide

How to choose a benford's law calculator

When picking a Benford's Law calculator, consider whether you need guided interpretation or just a raw frequency comparison. If you are new to the concept or working with a small dataset, a tool that explains the chi-square result and includes sample data helps you understand whether your numbers actually follow the expected logarithmic pattern. If you already know what you are doing and just need to paste in your own list and see the digit frequencies, a simpler calculator without built-in examples will get out of the way faster.
