Web2.4 - Other Pairwise Mean Comparison Methods. Although the Tukey procedure is the most widely used multiple comparison procedure, there are many other multiple comparison techniques. An older approach, no longer offered in many statistical computing packages, is Fisher’s Protected Least Significant Difference (LSD). WebC. Unplanned pairwise comparisons. Tukey's Honestly Significant Difference. Tukey's test is a simultaneous inference method. If sample sizes are equal, it uses one range value to calculate the same shortest significant range for all comparisons. It is the most widely used method to make all possible pairwise comparisons amongst a group of means.
