StatKey can be used to construct a randomization distribution for a single mean, single proportion, difference in means, difference in proportions, the slope of a simple linear regression model, or a correlation (Pearson's r). Minitab can conduct a randomization test for a single mean, single proportion, or difference in means. Randomization Dotplot ofp̂1 — p̂2Null Hypothesis: p1 = p2. skip diagram.
