Benford's law is the observation that for many datasets, the distribution of their first significant digit follows a non-uniform law; the probability that is the leading digit is .

## Details

In this Demonstration, the first control is , where is the Boltzmann constant and is the system's temperature. This Demonstration shows clearly that for both distributions, the distribution of the first digit conforms approximately to Benford’s law with only slight fluctuations. By changing , you will find that the blue points oscillate periodically around the stationary red points. Another statistical law, the Bose–Einstein (BE) distribution, conforms to Benford's law exactly at all temperatures and therefore is not included here.
