Visual verification of the properties of pseudorandom sequences
Sažetak
This paper describes properties of graphical presentation of pseudorandom number generator. Numerous more-or-less rigorous tests for randomness are available in the literature, and some of them are presented here. It is shown that both graphical and analytical tests give almost equal results, but graphical tests are simpler and closer to human perception. Because of that properties, visual tests combined with simple statistics are proposed as optimal for undergraduate higher education curricula. Mentioned methods are used on multiple courses at professional study of electrical engineering at the Polytechnic of Zagreb.
