For all the people asking why he minused 5 from all the values... It is called "CODING". It is a property of ANOVA. If you divide, add, multiply or subtract all the numbers by a common number, your values will not change...
Excellent Dr Puspendra. Your step by step teaching with solved problems helps students learn things on their own without any ambig ambiguity. For instance, crop yields are recorded with urea (fertiliser) applied in two different doses in a paddy field and Sample results showed increase in yield with increased dose of Urea (fertiliser) in experimental field A and field B. In field A 20 kgs of urea was applied and in field B 40 kgs of urea was applied in field B. Sample results showed increase in grain yield (variance) in field B than field A. The calculated F test is lesser than F table result. Can we conclude that paddy grain yield increases with increase in Urea (fertiliser) applied?
Sir, can you give some intuition why we are doing this? I mean explain the steps, why we are following these steps, what is each step doing. What's the significance of each term? If possible.
The tabular F value is calculated with (degrees of freedom of column),MS within. likwise in row part also. Why have u used (dfc,Residual) combo? It should have been (2,11) and (3,11) but you have calculated (2,6) and (3,6), please explain why?
If SSE is zero does it mean that within the group (Column and Row respectively) the variability is zero? but one can observe variation within the groups for both factors. Kindly explain this concept.
Sir, how to determine which particular row or column has significant difference from rest of rows or columns. In industrial applications, we need to determine which particular combination is working better and from rest of the trials. It would be very helpful if you can provide more insight on it ..
Sir , in two way anova followed by post hoc test, pairwise comparsion will be done with estimated marginal means or not. Assign compact letters by compariong estimated means with observed means of each group member
Good presentation.... Thanks a lot...... can we do 2 different 1 way annova for 2 independent variable and get the same result as above... please advise
that means that there is a significant difference between the variance and alternative hypothesis is true. when calculated f value is less than or equal to tabulated f then null hypothesis holds true
SSE ka df galat hai. SSE ka df nikalne ke liye "df=total N - total number of group" ye formula use karna padta hai. ye example galat hai, interaction effect nahi nikala, isliye apka last answer bhi galat hai,, last step total galat hai, book padho achese, phir aise lecture dena. Aisa example ho bhi nahi sakta.

your way of teaching is very comprehensive and your dealings with too much difficult subject (statistics) is very efficient sir g

Thanks, all of your 25-26 videos on hypothesis testing were helpful.
Thank you sir, this vedio is very helpful for us, to understand 2 way ANOVA test.
Best teacher i had ever seen in my life😍
Excellent tutorial, Sir why didn't you solve for the interaction?
Why 5 was taken as MID VALUE , Why not 4,6,7 or 8.
These are the fundamentals which should be explained ?
your choice
It is assumed ur assumption can be anything
Sir how u have taken nA ,nB,nC,nD value as 3
Sir, can you give some intuition why we are doing this?

Sir why you have taken 5 in calculation of grand total
That's the Assumed Mean 5
What if we calculate the real mean for the each row and column and apply?@@kshmasingh8263
sir if one value is missing what to do
why subtracted 5????
This is wonderful....thanks sir
Brilliant ✅💜

Glad to know 👍🏻
Thank you for the appreciation.
Keep studying and Share the Video Links with your friends and help us to spread the knowledge. ❤️💜💙💛💚
@@pkclasses100 thanks a lot sir. will definitely do so. :)
Nice explanation
I hav a doubt..? How we took degree of freedom1 as 6
Colum is 4 & row is 3
Good presentation.... Thanks a lot...... can we do 2 different 1 way annova for 2 independent variable and get the same result as above... please advise
Sir I had a doubt why should we only take 5as mid value
I have the same doubt
Sir..pl let us understand why you take 5 instead of 7,9
Same doubt yaar
Same doubt here 🤔🤔
U can take any other value too...the answer will be same
Hi sir, how you chosen the v1 and v2 values? Can you please explain me?
Awasome class sir ...!
If it is possible please provide MCQ on ANOVA.
Excellent sir. Thank u
sir plz help me how you calculated the tabulated value
plz
Great writing and explanation
Sir exam koi k mid value ley sakhte anser same hoga plss sir reply kro

Great! Are residual error and interaction the same?
iska answer wrong hai,............................interaction effect nahi nikala, isliye apka last answer galat hai,, last step total galat hai,
Are residual error and interaction the same?
answer is not same. it is different.
Thank you 😊
Thank you sir, Aapke bharose hii PG karr Raha hu, aap hii lectures class mein chalte hai
Thanks sir 👍 and it's very useful sir
If f calculated value equal to f tabulated value means what is the production??
Equal or less then null hypothesis is acceptable. But in such cases you can go to the 4th or 5th place of decimal and you may get difference.
Hello fams! Pls how did he get Fvalue of U1 as 6
Thank You Sir ❤️
please use single pen, it will be time saving and please tell us what does the terms actually mean rather than doing simple calculations
Why you have chosen 5 as the middle number
SIR can we randomly select the mid value ? explain it sir plz
Sir apne 5 kese leye minus jab keya plss btao sir exam hai
well explained
F(0.05) kaha se aaya sir
Thank you sir
Sir can we put the other values like 4 7 9?
sir F tabulated apne (2,6) ke corresponding liya ...jabki apke solution ke according (v1, v2)= (6, 2) alag value h table me ..
plz check
You are seeing from which table and what is the value?
Sir why you take the grand value 5 please sir
While calculating grand total, why did you take the value as 5?
you can take any value it wont change your answer 5 was just taken to make our calculation easy.
Calculated f value is more than tabulated f value than what's the solution for that
that means that there is a significant difference between the variance and alternative hypothesis is true. when calculated f value is less than or equal to tabulated f then null hypothesis holds true
Where it is 5
Thank you for such a clear explanation.
jo board par likha hai wo clear nahi dikh ta hai sir
Why we minus with 5
how v1=6?
When we chose mid value randomly then also we get same answer
Hello sir. Where was the value of 5 in the first calculation for grand total taken from?
you are so cute.
@@essa9865 Chutiye Zaatu
It's a mid value

Aisa example ho bhi nahi sakta.
i think so too
Sir, what is 0.05 in tabulated value?
its level of significance, i.e. 5%
Also check 0.01
Ye 5 kese liya
grant table me hr jagah 5- value kiya hai phir d column me tuesday me value-5 kyu kiya hai
How did you get v1=6?
(c-1)*(r-1)
Calculation of gt is complicated
sir why is the numerator (18:34) 6?
(c-1)*(r-1)
at 7:23 why did you subtract by 5? can anyone explain?
