Dataset of 5000 points

PiDigits

218 observation of 1 variable:

This dataset consists of the first 5000 digits of the mathemtatical constant pi (= 3.1415926535897932384...). These 5000 digits were reported in Mathematics of Computation, January 1962, page 76. Interesting number-theoretic questions involving pi digits are 1) are the digits uniformly distributed? and 2) is there serial correlation between successive digits?
