Abstract:

The randomness of a table of a million digits produced by a random digit generator was examined by applying four tests. The four tests were 1 Frequency test, 2 Poker test, 3 Serial test and 4 Run test. The complete table of a million digits was subjected to the first two tests. The last two tests were applied to a sample of 50,000 digits from the table. All computations were accomplished by means of I. B. M. equipment. There was no evidence of any unusual divergence from the theoretical expectations in any of the tests. It would be difficult to construct a series of digits which would succeed in evading all four of these tests. The examination of the million digits did not reveal any bias. There was nothing to indicate that the digits were not being produced with equal probabilities.
