Benford's Law describes the distribution of leading digits in many real-world numerical datasets. What distribution does it predict?
Hide and think first
A.
The leading digit follows a geometric distribution with parameter
1/9
, favoring small digits exponentially
B.
The leading digit is uniform over
{

9
}
, each occurring
1/9
≈
11%
of the time
C.
The leading digit is Gaussian-distributed with mean 5 and standard deviation 2.6 on a rounded scale
D.
The leading digit is
d
with probability
