RECKANOWHERE I'm glad I'm not the only person who felt this way! As Einstein once said " If you can't explain it simply, you don't understand it well enough. I'm seen many videos about ANOVA's and they were ok at best. This video is excellent! Very impressed
Brilliantly explained! This 4+ minute video was more effective for me, in terms of understanding what exactly ANOVA is and its function, than my entire semester. Thanks!
After taking many stats courses this is probably the best video I have seen to understand the concepts. Its a shame that our teachers get so lost in formulas and the "old way" of doing things. Thanks for breaking it down simply so if people want to know more they have an idea of the basic concept.
Yes. People are often following rules too strictly. When you are teaching basics, you can even cut corners and make false claims, if that makes the basic consept easier to understand. When that is achieved, you can start teaching details. If you try to use correct terms and mathematical symbols all the time, it just makes things much harder to understand for no reason.
You are an outstanding teacher. Not just mindlessly going through the steps but making connections in a logical way. Thank you so much for this video!!
J David Eisenberg Hello sir, I am having airborne dust concentrations data as PM10, PM2.5, PM 1 . These data was taken before and during dust producing work in a civil construction site. N=5 How can i compare these before and during operations data ? It seems that there is percent variation in dust concentrations in atmosphere between before and during operation data based on particle size. Before operation: PM 10 ( particle size less than 10 microns) is sharing 40% of total airborne dust, and PM 2.5 ( particle size less than 2. 5 micron) shares 10% of total airborne dust. During machine operation: PM 10 shares 60% and PM 2.5 10% only. It seems that PM 10 share is increased due to that machine operation? Which test is suitable for analysing these type similar data for discussion ? How to use statistics? Any comparison among these particle sizes? thank u.
David, I teach stats at grad and pos-grad in the UK and your video is the best explanation I have come across for ANOVA. I couldnt do it better. I will be using your video in my online course at Liverpool John Moores University, UK. It would be great to have your slides but I expect that might be too much to ask. Thank you for this wonderful video
This is a fantastic explaination! I have been struggling to comprehend the essence of this method until I watched this excellent work. I actually just passed midway and had to pause the video to make my first RUclips comment this year. Well done!
dont know if anyone will be reading this but, this video, for my exams when I didnt know a thing about anova, was a lifesaver. thanks for posting LOTS OF LOVE FROM NEPAL :)
1:40 if you're confused about the caption being opposite to what is said then make sure to see that it's not "can reject" but it's "can't reject" which is same as "accept" as said in the audio
Absolutely great video! Understood what ANOVA is about in such a short period of time, good examples (also with the more variables at the end), thumbs up!
Hi David, Great video. Your intuition is correct...if there are only two groups, an ANOVA will give the same result as a t-test. The actual value of the F statistic in that case will be the square of the value from the t-test, but the conclusions reached will be the same.
If the test statistic is not farther out than the critical value, all we can conclude is that we cannot reject the null hypothesis. Hypothesis testing is done assuming the null hypothesis is true (that in some sense fixes the distribution of possible test statistics). So in this case we simply would not have proof that there is a significant statistical difference or effect. That is not a proof of equality/no effect - just that equality/no effect is still plausible.
In your case, an independent samples t-test would be best, as it is designed for a two-group situtation. I haven't done the math on this, but my intuition tells me that an ANOVA on two groups would come out to the same result.
3:15 Do you mean that the reason you can reject the null hypothesis because the p-value is less than .05? Does the amount of F-value really matter when deciding whether to accept or reject the null hypothesis?
No, not necessarily.Let's say you have F(6,6). The 1% level would be 8.47, and the 5% level would be 4.28. So, if your F statistic came out to 6.19, the significance would be somewhere between 1% and 5%. If you're using a statistical package like SPSS or R or SOFA, it will give you the exact p-value, so you won't need to use a table.
I find it funny how he says we accept the null hypothesis and the subtitles say we can't reject the null hypothesis. The correct answer is left as an exercise to the reader.
The correct interpretation is that we cannot reject the null hypothesis. Changing subtitles: easy. Changing audio: requires re-making that part of the video and uploading a new one, thus destroying the old one.
i liked the easy explanation. so to be sure if there are more then two groups we can use ANOVA and if there are less than two, then we can use Z-test or t-test.
what s a reaction time? the needed time for them to react either they like it or not? the needed time for them to feel hyped or relaxed or for whatever reaction the drink has on their bodies ?
They’re not reacting to the drink. You’re giving them the drink, then giving them a standard test of how fast they can react to stimuli. Usually this involves flashing a stimulus on the screen and seeing how long it takes the person to press a key on the keyboard. (Do a search for "reaction time test" to see an online version of such a test.)
Once you have the F-value, you look it up in a table that tells what the probability is. The probability is the probability that, if you did this experiment over and over, that you would get these results purely by chance -- in other words, the probability that there is no effect of the type of drink on reaction time.
You did an excellent job on the ANOVA presentation. Would like to also see one like this for MANOVA. We are just now beginning to study these in our doctoral classes. Thank you for your excellent work.

Probably the best explanation on one way anova I've seen. Thanks for posting.
RECKANOWHERE I'm glad I'm not the only person who felt this way!
As Einstein once said " If you can't explain it simply, you don't understand it well enough.
I'm seen many videos about ANOVA's and they were ok at best.
This video is excellent! Very impressed

How to use statistics?
Any comparison among these particle sizes?
thank u.
@@jdeisenberg very good teacher. Keep making videos, for humanity's sake!
Thanks for the kind words; glad you liked the video.
Thank you, this was super well made.
This video was amazing! Finally someone who has been able to communicate a complex test into simple terms and a great example. Thank you!!!!
amazing explanation! Couldn't understand ANOVA for weeks until this showed up. Props to you David, keep making these videos
by far the best and easiest explanation of ANOVA I've seen. Excellent Job
This was about as good and clear an explanation of ANOVA that I have ever come across. Really excellent teacher.
David, I teach stats at grad and pos-grad in the UK and your video is the best explanation I have come across for ANOVA. I couldnt do it better.

The simplest explanation for anova i could find. Thank you J David Eisenberg
Hays off the best explanation I've come across so far. Concise, good examples and everything covered.
Thank you kind sir.
dont know if anyone will be reading this but, this video, for my exams when I didnt know a thing about anova, was a lifesaver. thanks for posting
LOTS OF LOVE FROM NEPAL :)
That was the best explanation for ANOVA I've ever seen. Thanks a lot, absolutely grateful!
Best 4:45 minutes I've watched for ANOVA, thanks for this video!!!
This taught me more about statistics in
Really thanks a lot sir. The essence of teaching is the art of putting the complicated matters in simple words.
By far best ANOVA explanation I've heard...and in under 5 mins at that!
This is seriously the best simple explanation. Thank you so much for refreshing my memory.
Thank you for this simple yet CLEAR explanation of ANOVA. You're the best!
Explained the right way, no hidden tricks. Thank you, sir!
The best explaination..It took an hr in class but I wasnt clear....thanks Sir wonderfully simplistic explaination
This was super helpful for my practical statistics for educators class. You have a way of explaining it that actually makes sense! Thank you!
Your videos cleared out all my questions about those statistical tests. Thanks a lot!
Thank you so much! Finally, I understood what is ANOVA all about!Manyyyyyyyyyyy thanks!
Beautifully explained and in simple English. Thanks dude!
Simplistic demonstration of the key ideas of ANOVA. Well done sir!
Finally understand it! I wasted a whole week studying. Excellent job explaining.
I just read a 70+ page PowerPoint of nonsense, and then your video explains perfectly!
In 2 minutes I went from knowing nothing about ANOVA to "Wow, it's very interesting". Thank you sir!
1:40 if you're confused about the caption being opposite to what is said then make sure to see that it's not "can reject" but it's "can't reject" which is same as "accept" as said in the audio
The best explanation of ANOVA out there. I'm so lucky I found this video. Thank you so much!
Hands down the easiest to understand. Thank you so much, I'm so confused with this class, but you have helped me understand a lot better :)
It is very a good explanation of Anova, every teacher or professor should start with such explanation
This is one of the best explanation of ANOVA I have seen too. Thank you so much for the great post! : )
wonderful! I need pictures and simple words to get things, so this was by far the best video I've found on ANOVA! Thank you Sir !
Hi David, your explanation was one of the best I heard in a long time. Thank you. Now I can get back to my work.
Couldn't understand it from anywhere. Was about to leave this topic when saw your video. And now I can explain this even to a five year old.
Still the best explanation for a one-way ANOVA on the internet! Thank you so much!
Arguably one of the best explanations for the concept. Thanks so much.
Absolutely great video! Understood what ANOVA is about in such a short period of time, good examples (also with the more variables at the end), thumbs up!
Thank you as always...the best part is you actually reply and clear the doubts. Keep it up!
Thank you for making this understandable. the best explanation I have found after hours of searching.
Was linked here by my statistics professor. Nice and clear video.
Crisp and best explanation I've come across. Keep making more videos.
Ajay Kumawat is this One way anova
it is 100% accurate and precise to appreciate in statistical term. well done.
Amazing how this taught me an hours of jargon in few minutes🙏
Thank you for this video. I will include it for my students in a lesson overview before getting into the details of the ANOVA.
Thank you so much! This was by far one of the best statistics videos.
so far the best video for anova .thank you for the video
This is the best way to understand ANOVA. Thanks!!!
I haven't come across a better explanation ! Outstanding !
Hi David,
Great video. Your intuition is correct...if there are only two groups, an ANOVA will give the same result as a t-test. The actual value of the F statistic in that case will be the square of the value from the t-test, but the conclusions reached will be the same.
I am happy finally i could understand the logic and basic behind ANOVA thanks a ton
one of the best explanation about ANOVA. please do more!
one of the best explanation . Made is simple , yet so clear.
Brilliant, I can't believe how clear this is. I will refer everyone I know to this video. Thank you so much.
I will definitely tell my college students to watch this video. Excellent job.
I had no idea until I watched your video. Thank you and thanks for the two links you provided.
Best ANOVA video out there! Keep up the good work!
Best explanation on ANOVA sir !! Thank you very much .
Very very nice explanation in the easiest way and in shortest span of time.thanks
Nicely explained Mr Eisenberg thank you
If the test statistic is not farther out than the critical value, all we can conclude is that we cannot reject the null hypothesis. Hypothesis testing is done assuming the null hypothesis is true (that in some sense fixes the distribution of possible test statistics). So in this case we simply would not have proof that there is a significant statistical difference or effect. That is not a proof of equality/no effect - just that equality/no effect is still plausible.
What does the probability here signifies 3:05 ? Is it the probability of that ration being 4.27 ?
The exposition of the meaning of ANOVA is very clear!
clearest explanation I've heard/seen - thanks - you're a great teacher
Thanks. You really make the essentials of ANOVA clear!
This is the best video available on utube
This was a better explanation than Crash Course.
In your case, an independent samples t-test would be best, as it is designed for a two-group situtation. I haven't done the math on this, but my intuition tells me that an ANOVA on two groups would come out to the same result.
Thank you so much... 10 years later.
3:15 Do you mean that the reason you can reject the null hypothesis because the p-value is less than .05? Does the amount of F-value really matter when deciding whether to accept or reject the null hypothesis?
Yes, the F-value is the thing that matters - the p-value is based on the F-value and the degrees of freedom, not the other way around.
The best explanation of Anova. Thank you 😊😊😊
Hands down .. Best explanation ever !
Thank you that was a really good explanation! The visuals helped a lot and your pace was good
That was the best explanation I could ever hope for.
No, not necessarily.Let's say you have F(6,6). The 1% level would be 8.47, and the 5% level would be 4.28. So, if your F statistic came out to 6.19, the significance would be somewhere between 1% and 5%. If you're using a statistical package like SPSS or R or SOFA, it will give you the exact p-value, so you won't need to use a table.
Great Video. This is the best simple explanation of ANOVA.
Explained this better in 5 minutes than hours of my professor babbling.
You probably picked up enough information from the professor that the video summary allowed you to put all that information together.
Best video , better than professors in college ❤
You gave a very nice example to explain ANOVA test. thank you
you don't understand how this saved my life and degree you legend. i love you so much. if i ever see you in person i will kiss you. MY KING.
Thank you for the useful explanation. You made this so much easier!

yees i saw you've got a lot of great comments already but i'm gonna say the same : that was the best explanation i received on anova
Best way of explicating f-test, Thank a lot for this video

(Do a search for "reaction time test" to see an online version of such a test.)
thanks for your 4 minutes introduction of ANOVA.
Hm. I can easily change the captioning; changing the audio might be trickier. Let me look into it.
How did you get the probability as 0.04 at 3:05? What is it the probability of?
Once you have the F-value, you look it up in a table that tells what the probability is. The probability is the probability that, if you did this experiment over and over, that you would get these results purely by chance -- in other words, the probability that there is no effect of the type of drink on reaction time.
I really appreciate this. Very simple and helpful in preparing for the NCE.
The numbers that pop up at 3:07 aren't sufficiently explained.
You did an excellent job on the ANOVA presentation. Would like to also see one like this for MANOVA. We are just now beginning to study these in our doctoral classes. Thank you for your excellent work.
