Danny, I agree with your clear explanation because it highlights the role of statistical tests in validating group comparisons. Particularly, I appreciate your mention of training programs for positive trends since those are supposed to improve the skills if the participants after the intervention. Additionally, I think you made a point in how these tests help control errors, which is essential when making decisions. Because a result that appears significant, by the notable difference in means, could actually be due to chance if error control isn't properly addressed.
