Introduction to One-Way ANOVA

Показать описание

A brief introduction to one-way Analysis of Variance (ANOVA). I discuss the null and alternative hypotheses and conclusions of the test. I also illustrate the difference between and within group variance using a visual example.

In other related videos, I discuss the ANOVA formulas in detail and work through a real-world example.

No one explains it as clearly as you do. You are literally a life saver. Thank you so much

The only words that will keep on ringing in my mind are and . Great explanation !!

I simply cannot find the words to express my gratitude.
I am in a data science MSc and you are about to save my life...

You're AWESOME! LIFESAVER!!!! Thank you for making these videos, getting to the point, and showing examples!
I'd give you a million likes lol

Thanks! I'm glad you find them interesting. I may get to logistic regression eventually, but it might take a while.

As in many statistical inference scenarios, here the assumption of normally distributed populations becomes less important as the sample size increases.

So yes, for large sample sizes normality is not an issue. It's always still an assumption of the procedure, it just isn't very important for large sample sizes. And even in small sample size situations, ANOVA can still work well under some violations of the normality assumption, depending on the type of violation.

I'm brushing up on my stats and I wish ANOVA had been taught to me this way in the first place. Thanks for a great video in plain English.

Yes, it's done in Latex (a Beamer presentation). Thanks for the offer, but I think I'm going to keep this a one-person show. Cheers.

Perfect. Just what I was needing :-) I need explanations of the theory not the math. Thank you so much for this video!

please do a two ANOVA series as well man. i really appreciate your work.

...keep on going... your tutorials are so interesting~~~ cannot stop watching ^^ what about logistic regression, please make a tutorial video!!! ;)

Wait, where did you get that F statistic?

Cleisthenes

Professor--you reference the box and whisker plots and cite the mean. But I thought box and whisker plots display/mark the median. Therefore the "apparent" variances or spread are really about the median. Unless of course your box and whisker plots display/mark the mean and not the median. Your reply is requested. Thank you.

In the assumptions you say that he population should be normally distributed. Can"t we not avoid that and use the central limit theorem and find the same result?
