The first digits of data entries in most real-world data sets are not uniformly by distributed. The most common
first digit is 1, followed by 2, and so on, with 9 being the least common first digit. This phenomenon is
known as Benford's Law.
The table below is the probability distribution for Benford's Law where the random variable D represents
the first digit in a data entry.
