Regarding on the Mathematica documentation, SeedRandom offers several methods, which are distingushable in terms of degree of randomness I guess. Does anybody have a good idea, how to find the best method, when RandomReal should be used in order to get a set of bestly-uncorrelated values in a 100 x 100 Matrix like this:
RandomReal[{0, 1}, {100, 100}]
I don't think "degree of randomness" is a well-defined term. The different random number generators differ in which tests for randomness the do well on and which they do not do well on. There is no way to order them by "degree of randomness".
You don't change the way you call RandomReal and related functions to change the random number generator. You change the generator by making a call to SeedRandom and giving it a Method option.
