Class SiegelTukey


  • public class SiegelTukey
    extends HypothesisTest
    The Siegel-Tukey test tests for differences in scale (variability) between two groups. The test is used to determine if one of two groups of data tends to have more widely dispersed values than the other. In other words, the test determines whether one of the two groups tends to move, sometimes to the right, sometimes to the left, but away from the center (of the ordinal scale).
