Work Step by Step
$\textbf{The Scheffé Test}$
It's a post hoc (after the fact) test used to identify which group means differ after a significant ANOVA result.
It’s one of the most conservative tests, meaning it strongly controls for Type I error (false positives), especially when making multiple comparisons.
$\textbf{Tukey’s Honestly Significant Difference (HSD) Test}$
It compares all possible pairs of group means while controlling for Type I error.
It is ideal when you have more than two groups but want to compare two at a time.
It adjusts for multiple comparisons, reducing false positives.
