Random Generation: Analysis of the Responses

32 subjects attempted to generate 100 random digits. Their responses were measured using eight tests, the results of which were intercorrelated and factor analyzed. 32 simulated subjects were also generated from a table of random numbers and subjected to the same analysis. Three factors emerged from the human data: repetition, seriation, and cycling. These results support the 1970 analysis of Rabinowitz. It was suggested that these factors should be considered in any attempt to relate random production to a concept of randomness.
