We tried to approach the random number generation test as an applicati
on of chaos analysis. The randomness of numbers was well represented b
y their correlation dimensions calculated by Judd's method. We tried f
our methods of random number generation, and two of them (writing and
verbal) measured the activity of creating randomness in numbers. The o
ther two methods, which input the numbers to the computers directly, m
easured the activity of creating randomness in space. The comparison o
f age dependencies indicated that creating randomness in space is easi
er than that in numbers.
