Que : The following data represents the number of units of tablet production (in thousands) per day by five different technicians by using four different type of machines.
Workers | A | B | C | D
P |54 | 48 | 57 | 46
Q | 56 | 50 | 62 | 53
R | 44 | 46 | 54 | 42
S | 53 | 48 | 56 | 44
T | 48 | 52 | 59 | 48
(a) Test whether the mean productivity of the different machines are same?
(b) Test whether the 5 technicians differ with respect to the mean productivity?

Consider 1444/5 = 288.8, It was written 388.8 by mistake.
Remaining calculation is correct.
Only mistake in writing.
sir i m sorry but calculation of sse in this question is wrong because u said in previous video sse = sst- (ssc+ssr) but you are calculated in this question is sse= sst-(ssc-ssr)
if i m wrong then suggest me sir...
@Dr. Puspendra Classes, Sir the video lesson on ANOVA is explained very well by you. I have understood it . Thank you very much !!
Thank you prof! Your way of teaching is easy to follow through.
Sir Your teaching is so commendable..easily explanation of the topic with lots of examples...really really like your way of teaching
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. ❤️💜💙💛💚
Hello sir
Your whole statistics playlist has helped me a lot to prepare for exam.
You are great teacher and your hand writing is too good.
Thank you from nepal.
This video of your's is really very helpful. Thanks for this video
Oh I am sorry , actually after posting my previous comment , I happen to see the result of 1444/5 and then recalculated , now its ok . Thank you Sir.
Thank you so much sir. You made each and everything in anova so easy. God bless you.
Explanation of Two Way Anova is good for repition which has marked significant variation exists/ or not in columns/ rows reparately. That means it is answering 2 questions whether there is significant difference between columns or between rows.
Now i need to know how to find whether there is significant difference Between rows and columns together. Kindly reply
Thank you
Sir,Thank you for your videos . It was of great help
Is it possible to get Correction factor in negative value ?
Thank you so much sir!

Sir 50 ko he kyu lia 46 lete to poora answer change ho jaata h
Superb video
how to deal with blank cells, in a row few columns are blank for that i am getting an error, contains non-numerical alues ,i cant delete the row or column,please let me know how deal with it
Thanks sir😊😊😊
Sir is there any other short cut method
Sir, why you considered the frequency, v1 as 12? Can you explain me?
Sir..define hypothesis
Null and alternative
In Anova , is there any logic ? of accepting Null Hypothesis if calculated F value is less than tabulated F value.
That is a rule not logic.
Can you please tell whether mean productivity of different machines are same or not?
Sir, What about writing hypotheses for this problem?
You can take Ho and Ha by yourself no issues.... If you will see the video in a sequence then you might have learned how to write it.
Thank u so much sir.
Sir you are amazing ,your way of teaching is very niceeeee informative courageous ,very simple , easy to understand ....but sir .. I am unable to found your Videos on .. Binomial Distribution , Possion Distribution , Probability Theory etc topics ..please provide me a link
I haven't uploaded yet. But I will upload soon.
@@pkclasses100 sir please Upload that all the lecture soon .... because I have a mid semester exam in February and Final exam in March 🙏🏼🙏🏼🙏🏼🙏🏼🙏🏼
Sir why did you take na nb nc and nd in calculation of ssc as 5 shouldn't they be 4?
Sir how we find the difference between one way ANOVA method and two way ANOVA method
Sir, why you taken frequecy, v1 as 12
@Dr.Puspendra Classes
Sir can you tell me tha why we have taken v1 =12
Which ever is highest will become u1
Sir , In this problem the calculation of SSC , I am getting 438.8 and your solution says 338.8 . All of the steps of mine are same as yours. Then how it is possible?
Sir it's show to difficult to find weather its one way or two way
Sir didn't get how to take mid value sir can u explain please
Sir can you do a lecture on standard precipitation index (SPI)?
Sir in calculation of F ratio SST was not used then why u have calculated SST ?
For finding sse
At last from where degree of freedom v1=12 came?
it was of sse degree of freedom which we caluculated as residuals right ,we should use that degree of freedom to compare with remaining two degree of freedom
Which ever is highest will become u1
Why the mid value is assumed ? Kindly explain. Bcz, exact mid value is 51, and if calculated accordingly, then grand total becomes 0
You can take 51 also no issue... For easy calculation you can assume any mid value.
Once try it by taking other mid value. Final answer will be same.
@@pkclasses100 thank you sir.
Sir please circular Dichorism explanation is needed as soon as possible
3.49 kha se aya sirr , vo too explain kr dete
Why u have subtract from 50 ? It's not clear to me.
Yes, its not clear to me also....Will I get same answer if I take 51,52,53...What is range of numbers i can choose from?
Take the mid value...
here largest number is 62 n smallest is 42
so 62 +42= 104/2 = 52.
you can take any number near 52 for subtraction .
He has taken 50 for the sake of convience and to avoid more negative and large numbers
@@deepalpoonjani8404 thanks
@@deepalpoonjani8404 r u girl?
SIR,1444/5 = 228.5 and not 338.5 . I think the whole sum answer may change .
If so can u please post the correct answer
I will check it 👍🏻
1444/5 = 288.8, It was written 388.8.
Remaining calculation is correct.
Only mistake in writing.
why we substract 50 at the very first step
sir at 4:30 why we are taking 50 why not 40 or 30
helpful
can you upload a video showing latin square method today?
Not possible
no worries
Sir why v1 is not taken 3 and V2 is not taken as 12
Which ever is highest will become u1
Hello sir , what to do if level of significance is 15%
Follow the table to get the values
Yes sir , but the table which you have shown was for 5 percentage level of significance . How should I look if i want to find the tabulated value for 15 percent level of significance ?
Sir ANCOVA KI VIDEO BANAIYE
Anyone here for tomorrow's CSOE21 exam?
Edit: Today's exam, It's already 1 hr past 12 (⌣́_⌣̀)
