Webb13 aug. 2024 · The Tukey HSD test is a way of reporting ANOVA results and determining if the relationship between three independently varying quantities is statistically significant. It relies on first collecting values from a standard ANOVA test and then using specialized programs or sites for the Tukey HSD. WebbStep 4: Calculate the HSD statistic for the Tukey test using the formula: You’ll get MSE from the Anova output (MS error term); “n” is the number of items in one sample. Step 5: Compare the score you calculated in Step 3 with the tabulated value you found in Step 4.

WebbFirst, use the table at the right to determine the appropriate value of q at alpha = .05. The q value for this problem is Now, use the q value to calculate Tukey's HSD. Tukey's HSD is. Thus, the mean difference between any two samples must be at least to be significant. The top value is alpha = .05; the bottom (bold) value is alpha = .01. WebbIn the Tukey procedure, we compute a "yardstick" value ( w) based on the M S Error and the number of means being compared. If any two means differ by more than the Tukey w value, then we conclude they are significantly different.
