Benford’s Law is a statistical principle stating that in many naturally occurring datasets, the first digit of numbers is more likely to be 1, followed by 2, and so on, with decreasing probability. It’s used to detect anomalies in data by comparing the actual distribution of first digits to the expected distribution, aiding in fraud detection and data analysis.

Benford’s Law is a statistical principle that describes the expected distribution of leading digits (1 through 9) in many naturally occurring datasets. To create a table demonstrating this distribution, you can use the following format:
| Leading Digit | Expected Frequency (%) |
|---|---|
| 1 | XX.XX% |
| 2 | XX.XX% |
| 3 | XX.XX% |
| 4 | XX.XX% |
| 5 | XX.XX% |
| 6 | XX.XX% |
| 7 | XX.XX% |
| 8 | XX.XX% |
| 9 | XX.XX% |
In this table, you would replace “XX.XX%” with the actual expected percentages calculated based on Benford’s Law. These percentages represent the likelihood of each leading digit occurring in a dataset that adheres to Benford’s Law.
FAQs
What is the formula for the Benford law? Benford’s Law does not have a single formula. It is a statistical principle that describes the expected distribution of leading digits in many naturally occurring datasets. The law states that the probability of the first digit of a number being d is given by P(d) = log10(1 + 1/d) for d = 1, 2, 3, …, 9.
How do you use Benford law? Benford’s Law can be used to detect anomalies or fraud in datasets. To use it, you compare the actual distribution of leading digits in a dataset to the expected distribution according to Benford’s Law.
