A talented teacher is one who assumes the student knows nothing and can explain in the clearest, most simple manner . You are very talented, sir, and you are a great assistance to many students.

Thank you Eugene! I have my first stats test tomorrow and this is the most straight forward explanation I have seen so far! You Saved me.
P.S. I think you might have a future as a narrator if teaching stats gets old.

You are a very good teacher. Your explanations are very clear and easy to undertand especially for some like who doesn't like mathematics and never heard of these statistics calculations, like ANOVA. it sounded like supernova at first 😀and t-test? Thank you so much.
