What is ANOVA (Analysis of Variance) in Statistics ? | Explained with Examples (ANOVA F - test)

In this UA-cam video, we will be exploring ANOVA analysis of variance. We will cover the basic concepts of ANOVA, including the null and alternative hypotheses, the F-test, and the p-value. We will also explain the different types of ANOVA, such as one-way ANOVA, two-way ANOVA, and repeated measures ANOVA, and when to use each type.
So, if you're ready to learn about ANOVA and how it can help you make sense of your data, then this is the video for you!

Ans the questions

Replied

[@elsasusankurian5076]

If denominator degree of freedom is a bigger value (for eg.300 ) how can we find F critical value from table??

[@aminabadawy475]

Very comprehensive and simplified explanation , thank you

[@DigitalELearning]

Glad it was helpful!

[@mdontita]

Thank ❤ you so much.. after alot of days studying the unit, now am ok. 🎉🎉🎉🎉thank you very much.

AWESOME teaching, how to interpret the anova results for data, kindly explain

[@BrewsandViewsKe]

Amazing video!!! Very helpful

[@DigitalELearning]

Thanks a lot 😊

[@mirkenahirpha8572]

Nice presentation and the answer of the above question is C,B,A

[@rujenshakya5979]

1. F-statistic
2. Mean (eg: H0: Mean A = Mean B = Mean N)
3. Error (eg: Sum of squares within)

[@DigitalELearning]

Correct

[@musicalwanderings7380]

In your first example, I see a potential issue. When you calculate "within group" variation --> It can monotonically increase with increase in N. Whereas the numerator "Between group" only increases with increase in the number of groups. Increasing number of observations does not change it. That cannot be right. Something seems wrong.

[@praffulsinghal7140]

Beautifully explained sir..
Also, I want to know that in the same scenario if we Reject null hypothesis, then how will we determine the Best method to study (M1, M2 or M3) ?? Plz mention the name of the concept if there is any in statistics

[@fathimarasha8434]

I think it is post hoc analysis to understand significant group among others

[@lakshmikanthraman2220]

Hi team,
This platform is good to learn really.
Can you also share the flowchart to choose the right hypothesis test along with the condition to choose. It will be really added support to this video. Thank you.

[@DigitalELearning]

Sure will add soon

[@yahililugo2512]

great video ❤

[@KingWale]

Well done.
My answers to the questions are as follows:
1. C
2. B

[@surya9146]

Finally anova make sense 😊

[@DigitalELearning]

Hope u like it

[@chrisadrianachera7014]

Hello sir! Is it possible that the within groups is much higher than the between groups?

[@homark8928]

In other textbooks, they said ij is the jth obervation from group i

[@rabiaramzan9429]

Thank you sir 👍👍👍

Thanks

[@user-yk2ww7bp2q]

Thank you sir

[@DigitalELearning]

So nice of you ❤️

[@qinghuawang492]

Clear explanation.

[@DigitalELearning]

Glad it was helpful!

[@koiRitwikHai]

7:43 while calculating between group variation why you multiplied with 10? instead of dividing of by 3 or 2
moreover while calculating method A, B, C variance why you are not dividing the sum by 10? because variance is (xi - mean)^2/(n-1)

[@shivamduttsharma1812]

Good explanation. 😊

[@DigitalELearning]

Thank you 🙂

[@filzasaeed275]

How was the overall mean taken out

[@krishnayedage4209]

Thanks

[@DigitalELearning]

Welcome Krisjna

[@ankushghosh8693]

Nice 👍🏻

[@DigitalELearning]

Thanks ✌️

[@amrataly]

Very informative 🙏👏

[@DigitalELearning]

Thanks you so much . Appreciated 😎

[@d.sharon4654]

variance between/variance within if >1 accept h0 , na? if

[@DigitalELearning]

variance between/variance within if >1 Reject H0 and if variance between/variance within if

[@fathimarasha8434]

For variance we need degree of freedom also right?

[@DigitalELearning]

Not for variance but when u r calcuating F (critical)

[@khushipathak1821]

Nice video

[@DigitalELearning]

🙏

[@RoxanaIoanaDruc]

sorry at first one, is not 0.2 is 03... maybe I am wrong, but i calculated :)

[@DigitalELearning]

please re calculate it again

[@manasakadaveru7619]

Can you create of Two -way anova plz explain

[@DigitalELearning]

Sure I will upload soon

[@nishantpawadia9665]

1....f test 2....mean 3....error

[@hadimuhammed1892]

Hello man, your lecture is really interesting. I wonder if you could let me know what software you used for preparing this nice presentation.

[@DigitalELearning]

Thanks

[@DigitalELearning]

I use Powerpoint

[@rishabjoshi2366]

Thanks sir learned so much from ads just your video getting in between ads so that was boring.

[@DigitalELearning]

Sorry to hear that

Q1 is correct but not the Q2 and Q3 please try again

wee mzee ... that example did not factor in dividing by its df... Is that how its supposed to be done or there was a mistake

[@DigitalELearning]

Yes that is how it should be done

[@danielashishjohnson9513]

not helpful👎👎 you didn't quite explained clearly how you calculated the between group variation in the first example😡

Q1 c) By Calculating F statistics
Q2 : a) Mean
Q3 : a) Error

[@loganreed1904]

you says Num. Degree of freedom= no. Of samples = 3, whereas there are 30 samples divided equally among 3 groups, so you mean to say 3 groups? Also care to explain the degree of denominator freedom? Coz un that you said "sum of values" 9:07

[@aditimishra8278]

Try to explain it instead of reading please

[@DigitalELearning]

Thanks for the feedback

[@barkhaify]

But this wasn't quite the whole thing. Only generalized explanation.. include proper formulas and application.

[@DigitalELearning]

Sure I will

[@littlecutiepiedia2940]

C , a and d

[@DigitalELearning]

partially correct 1c, 2a, 3a

[@ankurbuc]

Wrong explanation of variance. You should have divide sum of square by number of observations. With your way it will always come less than 1

[@khushboo6717]

C;B;B

[@DigitalELearning]

Q1 c) By Calculating F statistics
Q2 : a) Mean
Q3 : a) Error

[@musicalwanderings7380]

Overall mean is not mean of means....
Let 3 means by x/N, y/N, z/N (where x,y,z are sum of observations in each group).
Overall mean = (x+y+z)/N
But mean of means would be (x/N + y/N + z/N)/3 = (x+y+z)/3N

[@Apk39557]

The are the same overall mean is (x+y+z)/3N.
See that 3N is the population size
