First Digits Rule! (Benford's Law)

2 hours ago

1. How often would you expect a "1"to be the first digit in a set of numbers? Well 1 is just a number like 2 to 9, right? So it seems like it should be the first digit 1 out of 9 times (about 11%): But no! A man called Dr. Frank Benford discovered that in many cases, the number 1 is the first digit about 30% of the time. And the poor old number 9 is the first digit only 5%of the time. Dr. Benford found this amazing thing also happened with baseball statistics, areas of rivers, population sizes, street addresses and many more cases.

3 hours ago There’s a certain logic to Benford’s Law. A number that begins with 1 needs to increase by 100% to become a 2. A number that begins with 5 needs to increase by 20% to become a 6. A number that begins with 9 needs to increase by 11% to become a 0. That is, an increasing number spends more time with 1 as the leading digit than 2, more time

Benford's law Wikipedia

5 hours ago

1. A set of numbers is said to satisfy Benford's law if the leading digit d (d ∈ {1, ..., 9}) occurs with probability 1. P ( d ) = log 10 ⁡ ( d + 1 ) − log 10 ⁡ ( d ) = log 10 ⁡ ( d + 1 d ) = log 10 ⁡ ( 1 + 1 d ) {\displaystyle P(d)=\log _{10}(d+1)-\log _{10}(d)=\log _{10}\left({\frac {d+1}{d}}\right)=\log _{10}\left(1+{\frac {1}{d}}\right)} The leading digits in such a set thus have the following distribution: The quantity P ( d ) {\displaystyle P(d)} is proportional to the space between d and d + 1 on a logarithmic scale. Therefore, this is the distribution expected if the logarithms of the numbers (but not the numbers themselves) are uniformly and randomly distributed. For example, a number x, constrained to lie between 1 and 10, starts with the digit 1 if 1 ≤ x < 2, and starts with the digit 9 if 9 ≤ x < 10. Therefore, x starts with the digit 1 if log 1 ≤ log x < log 2, or starts with 9 if log 9 ≤ log x < log 10. The interval [log 1, log 2] is much wider than the interval [log 9, l...

Frequently Asked Questions

How did i find out about benfords law?

Benford’s law – Wikipedia, the free encyclopedia. I heard about Benford’s Law this weekend via a fascinating Radio Lab podcast on numbers. I came home and tested a few series of numbers and naturally enough they matched Benford’s Law. Below is the distribution of the first two hundred Fibonacci Numbers.

When is the distribution expected in benfords law?

Therefore, this is the distribution expected if the logarithms of the numbers (but not the numbers themselves) are uniformly and randomly distributed . For example, a number x, constrained to lie between 1 and 10, starts with the digit 1 if 1 ≤ x < 2, and starts with the digit 9 if 9 ≤ x < 10.

How does benfords law apply to fibonacci numbers?

Benford’s Law and Fibonacci numbers. Benford’s law, also called the first-digit law, states that in lists of numbers from many (but not all) real-life sources of data, the leading digit is distributed in a specific, non-uniform way.

How does benfords law work in a data set?

Benford’s Law can recognize the probabilities of highly likely or highly unlikely frequencies of numbers in a data set. The probabilities are based on mathematical logarithms of the occurrence of digits in randomly generated numbers in large data sets.
