Examination of Proper Randomness of the Numbers Generated by Rand Corporation (1955) Random Number Table: t-test

Abstract

Proper randomness of the numbers generated by Rand Corporation has been tested by B.K. Sarmah, D. Chakrabarty and N. Barman, IJESM 5 (1) : January – March, 2015, 97-119 by applying the Chi-square test for testing the significance of difference between observed frequency of each of the digit in the table and the corresponding theoretical (expected) frequency . In this paper, the randomness of the digits have been tested by applying t-test for amount of deviation of the observed number of occurrences and the theoretical (expected) number of occurrences of the respective digits and hence the numbers. The test shows that the numbers generated by Rand Corporation deviated significantly in most the observations from proper randomness.
