Generating Random Sequences
This mathlet allows the user to input a sequence of 0's and 1's of length 20 and then tests the sequence for randomness using three tests: Kolmogorov-Smirnov, Wald-Wolfowitz, and Mann-Whitney. An overall assessment of how likely the sequence was generated randomly is given, as well as basic information on how the tests work.
Probability, Game Theory, Statistics
This applet was written for a game theory course to demonstrate how difficult it is for people to generate "random" sequences in the context of playing mixed strategies. It has also proved useful in showing the sensitivity of several commonly-used non-parametric and runs tests. Users simply enter a series of 0's and 1's, and the applet reports the results of three statistical tests, along with a more user-friendly (and subjective) determination of whether or not the sequence is likely to be random.
