Example Sentences
- "The following argument can give an intuitive feeling for Benford's law.¹¹ Consider a set of numbers x, which are randomly chosen in the interval between 1 and 10. All x between 1 and 1.999 have 1 as the first digit, all x between 2 and 2.999 have 2 as the first digit, and so on. The ratio of the largest and the smallest x is (almost) 2 in the first interval. In the next interval it is 3/2, followed by 4/3, and so on, up to 10/9. The widths of the intervals decrease as in a logarithmic scale. There is more “room” for a number between 1 and 2 than there is between 8 and 9. [In other words, the numbers between 1 and 2 are more dissimilar to one another, quantitatively (regarding how big a factor it takes to get from one to another), than the numbers between other consecutive-integer pairs.]"
