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. WebThe confidence interval for the difference between the means of Blend 4 and 2 extends from 4.74 to 14.26. This range does not include zero, which indicates that the difference between these means is statistically significant. The confidence interval for the difference between the means of Blend 2 and 1 extends from -10.92 to -1.41. ray bradbury autograph
