Is Tukey HSD the same as Tukey-Kramer?
Note that the Real Statistics Tukey HSD data analysis tool described in Tukey HSD actually performs the Tukey-Kramer Test when the sample sizes are unequal. This example is the same as Example 1 of Tukey HSD but with some data missing, and so there are unequal sample sizes. …
How do you find the critical range of a Tukey-Kramer?
The pooled variance can be calculated as the average of the variances for the groups, which turns out to be 19.056. Lastly, the sample size of each group is 10. Thus, our Q critical value can be calculated as: Q critical value = Q*√(s2pooled / n.)
Which is an example of the Tukey Kramer test?
Example 1: Analyze the data in range A3:D15 of Figure 1 using the Tukey-Kramer test to compare the population means of women taking the drug and the control group taking the placebo. This example is the same as Example 1 of Tukey HSD but with some data missing, and so there are unequal sample sizes.
How to do two factor ANOVA in Tukey?
This is done by pressing Ctrl-m, double-clicking on the Analysis of Variance option and selecting the Two Factor ANOVA Follow-up option (as shown in Figure 1 of Real Statistics Support for Two Factor ANOVA ). After pressing the OK button, a dialog box similar to that shown in Figure 1 will appear. You need to choose the Tukey HSD option.
How to do the first Test in Tukey HSD?
For example, to produce the first test in Figure 2, follow the following steps: Press Ctrl-m and select the Analysis of Variance option (or the Anova tab if using the Multipage interface) and choose the Single Factor Anova option. A dialog box similar to that shown in Figure 1 of ANOVA Analysis Tool appears.
How to calculate 95% confidence interval for Tukey HSD?
From Figure 1 we see that the only significant difference in means is between women taking the drug and men in the control group (i.e. the pair with largest difference in means). We can also use the t-statistic to calculate the 95% confidence interval as described above.
