Equation of The Lines of Regression | Sample means X and Y | Correlation Coefficient Between X & Y

[@halima009]

I was having difficulty understanding this, but the way you cleared my doubt was amazing.

[@sanjoymaity6446]

College main 1 hour ka lecture or calculations ke bad vi nahi samaj aya lakin yr 15 min ka ye video..... 👌wah sachmain kamal ki ho up sir 🙏🏼

[@chuangrongmei5168]

Y calculating in calculator.... I want to knw how to find the X n Y

[@abhishekganapure6456]

Nigga do it manually 🔪

[@shishirshikhar5462]

B) For the variables X and Y, the equation of regression line is 4x-5y+33 = 0 and 20x- 9y
=107. Identify the regression lines. Find co-relation co-efficient, X¯, Y¯ and oy. If
variance of x is 9.

[@shishirshikhar5462]

Sir iska answer milega

[@agentx5453]

Ajj mera viva tha.. Tunhare ye video na bacha liya mereko m ❤️❤️

[@mechc06saurabhjoshi6]

Thanks Sir.. 😀
You Clear My Dout.. 👍

[@Deepali9955]

Bahut aacha bataya h aapne thanku

[@champ2228]

You made my day. Thanks friend.

[@deviknakar5052]

How did you calculated 3&0.5 while using calculator

[@triparnasarkar8633]

That's my question also... Everyone doesn't have this calculator...

[@ashudii]

@@triparnasarkar8633 Use Casio Fx-991ES calculator or you can solve it by option Mode and then Equation 👍

[@sumitmakadiya3119]

​@@triparnasarkar8633 lol its just a simple root of both line you just need to solve both equation with any method then you will geet values pf x and y

[@triparnasarkar8633]

Okkkk.... Thank you😐

[@questionpaperfriend9215]

caymars rule

[@DrawingwithPrerna]

if var x =3 ; find standard deviation of y?
ye part kese krenge

[@SalomaMathew]

Amazing u explained well and it seemed easy thankyou so much liked😃

[@bhawanabhatt4369]

If bxy or byx is positive and another is negative then
Plzzzz answer

[@Anonymous-k9m7g]

Both of equations give only one value not two if he assumed x on y
And y on x it's not a best approach to solve that type of questions, you can watch another video

[@luchiNalo]

nhi semjaa hai x bar kis nikla

[@samu.k5293]

Thank you

[@ronitnandy1861]

sir isa mehod se marks milaga na
\

[@anjuchoudhary2860]

Very good explanation

[@RakeshKumar-et2vf]

Can you tell me how you find the mean value of X and Y .

[@crisistg7315]

Using calculator

[@zeeshanali6738]

If the equation of the regression line is y=-03x0.4, then the correlation coefficient between the two variables will beً??( positive or negative)

[@Jayjadhav-k9y]

Sir mere example mai 1 equation mai value 1 se choti hai hi nhi fir kya kare

[@entertainment-ke6rc]

7. Given the two equations for regression lines :
8x - 10 y + 66=0
40x - 18 y- 214=0
(i) Identify the regression lines of Y on X and
X on Y.
(ii) Obtain regression coefficients and the
correlation coefficient .
(iii) Find the mean of X and the mean of Y
(iv) Given the standard deviation of X =4 , find
the variance of Y.

[@DrawingwithPrerna]

last part variance wala kese hoga

Its may helps

[@ramuacharya1254]

Thank u so much.

[@DrawingwithPrerna]

Thank you sir

[@wwyou-we2283]

Thankyou sir

[@sarthakhukkire9325]

Under root Mai 1 value ( -) Aa gayi to kya karne ka?

[@sandeeprajr4125]

Helpful 👍

[@kaustubhjagtapa1364]

Sir Agar Sirf Correlation Coefficient Nikalne Keliye kaha toh Kya karne Ka ?

[@harshalthakur6153]

1 se kam hi chahiye kya?

[@paravoid5665]

Your rule didnt work for my question ??

[@sarasanpola5807]

Plzz tell me the answer question is ,
If the correlation coefficient between the two Variables X and Y is 0.4.then the correlation coefficient between X+3 and Y-5 is _________? Plzz answer me🙏

[@deviknakar5052]

Can you tell me the answer
3x+2y-26=0 and 6x+y-31=0

[@rohinebasani5149]

What is the r value say me I did

[@ManpreetKaur-tu2tb]

Sir mean hi smjh me nai aayi kese calculate kia apne

[@mustakma3204]

I didn't understand on calculator
Please can u do the calculation on paper

[@subhajitdas1882]

Can value of r be greater than 1?

[@DARKMATTER1113]

Never

[@Arjun_CCBP]

Sir what is the sign of r if Bxy is -ve and Byx is +ve

[@Jay_Sonar_Official]

-

[@mohammedashiq5210]

Is r can be greater than 1

[@the_golden_blush1378]

Sample means x bar aur y bar kaise calculator mein nikala samjha nhi

[@prasadpadwal2902]

Sir mere pass calcuter nhi hai o bata de plz sir

[@zafaralikhan1447]

x &y bar ka value kaise nikale samajh nhi aaya bhai

[@prasadpadwal2902]

Sir 1st step nhi samaj ayi plz sir bataye

[@prathamshetty938]

r ka answer positive hai sir

[@anantyadav4739]

Mast calculator use krta hai yeh

[@avinashKumar-ek4xv]

If the correlation coefficient between the variables X and Y is r , the correlation coefficient between X^2 and Y^2 is *

[@rohinebasani5149]

Please dont do in calculator bcz of that how can we write in exam do practically and show please

[@ayushthakur7566]

Bahut confuse kar diya bro

[@vyomgupta8877]

bro breathes with a calculator

[@AdityaKing-x7e]

worst video bhai shi se toh bata calculator se krna hota toh teri video kyu dekhte

[@gauravkapdoskar]

byx= -0.167

[@GaneshShegar]

Listen carefully what I told in video
+ Or - doesn't matter while checking for

[@CodingIsEntertainment]

Wrong

[@Chogyaltenzin-y2w]

Thank you sir
