First check out a couple of mathematical statistics text (such as J.E.
Freund's or J.D. Gibbons's), and look up "nonparametric" methods to see if
they will do what you want. In a typical undergraduate mathematical
statistics text, there is usually a chapter or two on nonparametric
techniques where they teach you a couple of tests based on the concept of
"runs". According to the authors, these non-parametric tests may be used to
test the randomness of observed data.
