Guys while finding 'r' try to take Bxy and Byx such that you get larger denominators ex: 2x + 3y=10 and 4x+5y=18 here we find correct r with byx=-5/4 and bxy=-2/3 so 4*3 (denominators) will always be greater than 5*2(numerators) hence we can get (r)
I don't have words for appreciate this level teaching , it's too much help full if anyone else watch it's clear every doubts thank you soo much sir... 🙏🙏

Sir u are really an amazing teacher..no less than an angel for students like me who understand nothing in the class because of so called highly qualified teachers..thanks a lot sir
Tommorow is my exam AND I am here to see you ThankYou very very much for your efforT I understand whole correlation and regression so clear... Love from NEPAL❣️
Sir ur teaching is very clear sir....but only thing u need to do is increase the clarity of video sirr.....and everything is very understandable..... go ahead sir..thank you

when we assume the regration equation of X on Y & Y on X to find a Corelation Coficiant(r) if our assumed equation is wrong than we can get the True ( r ) just take a inversion of ( r ).... so its time saving.

Hello Sir I am slow learner student I know the question I am asking to you might sound little silly to you but Can you give answer to the following question Statistical correlation is measured by coefficient of regression true or false. Please do reply Thanking you in anticipation
Sir in Q1 u have taken wrong value of bxy as the coefficient of y(bar) is 10 u have taken 18 in place of that so our ist assumption is correct for taking =ns as yonx and xony... And that yeilds the value of r=0.6. Thanks.
