Chapter 11: Anova introduction and example [1of4]

[superoriginalname]

Question, to prove that H1 is true F has to be greater than 1. My question is that due to variance being squared, can F1 be ever less than 1 to disprove Ho?

[PaperChayne]

@superoriginalname May be too late but the F value can never be below 1, and when it is bigger than 1 it disproves the Ho.

[palui]

@PaperChayne You *can* have an F statistic less than 1. Just look at the distribution. The way this guy set up the F statistic fraction was incorrect. An F statistic less than 1 just means that the the between group variance is smaller than the within group variance, which is more often true when the null is true.

@dannyvr91 ... that's not for the first years! :)

I'm a student from Moldova in the 3rd year.. . and i know it would be impossible for me to have taken such courses in the first year.

Go take some basic statistics before watching these videos!

I love this guy's courses! He explains well, and ... sometimes he says hilarious stuff! :) But he's good!
