Comparative Notched Box Plots.
Abstract
Comparative notched box plots are developed to provide confidence intervals and hypothesis tests for the two sample location model. The notches are confidence intervals derived from the sign test. Rules are given for assigning confidence coefficients to the notches to yield a 95 percent confidence interval and 5 percent two sided test for the difference in locations. The test that rejects no location difference when the sign notches are disjoint is shown to be Mood's median test. Circumstances under which multiple comparisons can be carried out are also discussed. (Author)
