Hi, i got confused with the statement at 3:14. "The larger the overlap, the bigger the F statistic." Shouldn't it be an inverse relationship like what the other slides say?

Thanks for putting this up. Very informative.

[ProfKelley]

Yes- you are right.

Why couldn't my statistics professor make ANOVA seem this easy? Your students are very lucky to have their levels of frustration reduced by such a clear and thorough teacher! I know lots of people in my class could use this video (and luckily someone linked it from our FB page).

Thanks for this very clear explanation. I'm hoping to see more of your materials!

THANK YOU Dr. Kelley. I learned more in 9 minutes watching this video than I did in weeks in a statistics class.

@bernd9000 you can use Excel to do an ANOVA test and it will calculate the p-value as well.
