The values in the table represent the Tukey HSD (Honestly Significant Difference) test results. Values above a certain threshold (determined by the Tukey table, sample size, and significance level) indicate a significant difference between the means of the groups. Since all pairs involving Monday (Mon, Thu), (Mon, Wed), (Mon, Fri), and (Mon, Tue) have values listed, it implies these pairs differ significantly.
