 "Benford's Law" is the basic premise that, in many statistical data sets, numbers with leading "1s" tend to occur more often than numbers with leading "2s"....and numbers with leading "2s" tend to occur more often that numbers with leading "3s," etc.

 

Here's a link to a brief discussion about this ..it starts at Part 7, about 1/2 way down the page....http://www.maths.surrey.ac.uk/hosted-sites/R.Knott/Fibonacci/fibmaths.html#relprime

Yeah, Melody.....weird and strange things do abound in the world....

Consider the "poiuyt," below  ....[courtesy of my good friend, Alfred E. Neuman ]

I'm not actually sure....but I'll tell you where it came from.....look at the top line of letters on your computer keyboard.....start with the "p"  and go back 5 letters.....what do you find???

It has to do with something called the "Power Law".....simply put....larger values in data sets ( such as tall mountains, etc.) are more rare than "smaller" mountains.

Consider the weights of most adults......most start with a "1" or a "2"....and there are fewer that start with a '3"....and fewer still that start with a"4".....

That's about as much as I know about this.....
