The David-Barton test. Assuming the scale model (equal medians), this test can be employed to test whether the two distributions selected have equal scale parameter (with the null hypothesis of equality). The David-Barton test ranks elements with the following weights: N/2 ... 3,2,1,1,2,3 ... N/2 for N even N-1/2 ... 3,2,1,0,1,2,3 ... N-1/2 for N odd An approximation to the Normal distribution is employed to compute p-values.
