Tp
Thank you so much sir ..
thank you sir
Thank you from Bangladesh
sir thank u so much bcoz of u i'm solving the questions and also my whole concept is clear
This 2 year old video is saving me right now
Cause my college professor doesn't know how to teach anything 🙂
Thank you
No exaggerated content. Precise and to the point lectures. These lectures are saviours during exams.
Thanks a lot sir❤❤.
Keep going 🔝📈
Halaki mere syllabus m to rank of correlation ni h lekin maza aaya padhne m ? K jis chiz pe hm log sirf behas mr sakte h usko sabit bhi kr sakte h with exact value.
Kudos maths🤩
Sir! In the Beauty, Contest Q I found Summation dyz = 214 I think there is a calculation error there if so KIndly confirm for others. Great Teaching Btw.
Yes i also got 214
yes it would be 214
You Know this video is 3y old
@Daredevil thank you so muck for confirming i rechecked 4 times thinking i have made an error

Love u sir u doing great job that is like donation for us in terms of knowledge
Sir your way of teaching is superb
sir the value of D^2yz is 214 not 216
vohi yr, mera bhi 214 a rha hai. bc muje apne answer ko recheck krne me adha ghanta phookar pata chala ki sir ki hi glti hai.
Hi sir, please make a video on how to calculate logistic regression, thank you
Sir your videos always make my exam awesome
Thanks sir for my doubt solving 🙏
Thankyou sir... your videos are fabulous dear sir..🙂🙂
Maths is easy with you sir .
Thankyou from my 💓
Thanku so much sir really saving vedio in the exam🙂🙂🙏🙏🙏

thank yoy so much sir
Thankyou so much, Sir
sir small correction. Σd^2 yz = 214 . and final answer for ρyz = -0.296
Thank you so much sir♥🥰🙏
nice explaination sir ..better than my proffessor
Thanks for teaching easy mathod
Thanks sirji
Thanks sir ❤
Think you sir
Great!
गुरुजी।
प्रणाम।
Amazing video.
Thank you sir......
Great video sir
thanks alot sir!
Thank you sir 😊👍
You are God of mathematics 🙏🙏🏻 🙏 🙏
Thank you sir !!!
Sir, For questionnaire(30 questions) on likert scale I want to want to find correlation between two group of respondent. How shall i do as there are 30 questions ?... I m not correlating the variables but the respondent..
Thanq sirr
I understood sir 😊
Sir the value of d²(yz)= 214.
Nicely sir
Thank you so much sir 🙏🙏
Sometimes I imagine, how difficult life could have been in engineering mathematics, if your videos were not present.
Regards from undergraduate second year mechanical engineering student of Jadavpur University.
Thanks sir...❤🙏
Really sir u r awesome 😎😎😎😎😎
Amazing sir
Thankyou sir🙏🙏😊
Thanx
Very good
Thank you sir 💗🇧🇩
Good explanation Sir.ji ♥️
Please mcq questions provided.
thankyou sir it's amazing lacture. Rishuraj from IIT DELHI
Thankyou sir
Superb 👌
Watching from nepal thnks sir
Thanks sir
Thanks🌹🌹🌹 sir
Sir,u r requested to prepare lecture on numerical method of partial differential equations
Thanks Sir 😃😃
Thank sir
Thnksss
can it be computed for all quantitative variables?????
it will be helpful if you can also derive the formulae in the video
Awesome
Best video
life saver tomorrow going to smash math's exam
Sir , in the second question 1st and 2nd judge both values are in negative then why are 1st and 3rd judges rank similar !??? Kindly explain this , I am unable to get this. Thank you.
Because negative value indicates that the 2 judges approach is going in different directions.. ie. When one gives higher marks then second gives lower. That is the relation. Negative relation.
If you still don't understand then go through the concept of negative correlation and positive correlation under types of correlation.
Then you will understand. Best of luck.
You are considering Pxy as 1st Judge, Pyz as 2nd Judge, Pzx as 3rd Judge. But x,y,z are 1st,2nd,3rd Judge respectively.Pxy is relation between the decision of x and y. Pyz is the relation between the decision of y and z. Pzx is the relation between the decision of z and x. As Pzx has a positive correlation therefore Judge x and Judge y will have the nearest approach to common test of beauty as their Decision move in a similar direction.
@@abhimat31 thanks 🙂
@@samratpodder545 yea , exactly u understood my problem. Thank you so much 🤗. Now I have no doubt.
@@samratpodder545 thanks for this. Really helped me
Sir m bht khusss hu aapki video dekh dekh kr mere Bsc 2nd year me math me 115 no aaye hai sir.. thanku so much sir....ese he sir Bsc 3rd year ke math ki bhi video upload kr do yrr sir plzz....
Good morning sir🎉
Thank you so much sir!
You're an amazing teacher!🙏❣
Thanks marel
@Dr.Gajendra Purohit - can we arrange the ranks from lower order to higher order? You are considering highest mark as rank 1. if we consider the lowest mark as rank 1 and highest mark as 'n' then will this ranking be valid?
Yes you can... Result will be same
