An important 20th century work in the field of statistics and random numbers was the RAND Corporation's book of tables containing, and entitled, A Million Random Digits with 100,000 Normal Deviates. It was produced in the 1950s by an electronic simulation of a roulette wheel attached to a computer, the results of which were then carefully filtered and tested before being used to generate the table. The RAND table was an important breakthrough in delivering random numbers because such a large and carefully prepared table had never before been available.

The main use of the tables was in statistics and the experimental design of scientific experiments.
