  1. Shows the significance results (estimate, standard error, t-value, and p-value) from running a post-hoc analysis using Tukey’s HSD test on clustering-related questions. There are several statistically significant differences in means for questions 13 and 17. The differences between the best and worst performers in questions 14 and 16 are also significant
