Last question la first,
equation number 1 la irunthu X (x on y) find panama
ean Y (y on x) find panuninga?
Suppose nan sona mathiri 1st X find panirunthal,
Ans 3/2 nu vanthurukum....
Can u clarify....

Thank u sir. I have understood.

Sir last sum la 1 St eqn na Y on X yeduthinga suppose X on Y yeduthal ans (3/2) wrong sir how to choose the eqn?

[@MathsNewSyllabusvarun]

We have to find correlation coefficient right so correlation coefficient always lies between -1less than Or equal to 1

[@MathsNewSyllabusvarun]

Thank you

[@kalaiarasikalaiarasi6984]

How to choose regression eq x on y
Or reg eq y on x from the given reg eqs

[@MathsNewSyllabusvarun]

you can choose any way but your correlation coefficient must be lies between -1 to +1

1st questions la direct ah X on Yr regression of coefficient apply panuna 0.4 ans varuthu sir. apadi apply panalama?

[@knowntounknowns5135]

Sir, i have a doubt. In the last question of this video dealing about correlation coefficient from reg lines. I am getting the answer as 3/2 by considering the first eqn as x on y and the second one as y on x. In which way, that is wrog

[@prabu3232]

r value (-1,1) value so 3/2 is not correct ok.

[@prabu3232]

@@Josphine13 correalation r value -1 and +1 between value ok va. R=3/2=1.5 so that is wrong.

Please tell sir.
I see ur videos last 3days only. So I missed lot of days to read same chapters.
Now only get ideas but time too short .

[@MathsNewSyllabusvarun]

don't worry sir...from each topic don't forget to read theorems,statements and definitions...plz don't waste 24 hrs per day...you can get success...from nex video i will tell you some standard books that will help you

[@kprithiviraj84]

Thank you very much for
Ur valuable support .
Please give guidelines and reference books for PG and POLYTECHNIC exams.
Daily I am waiting for ur videos sir and I give my maximum effort to prepare this PG exam.
Again thank you sir.

Sir first equationa la irunthu X on Y findout pannalama

[@MathsNewSyllabusvarun]

if you find this your corresponding correlation coefficient r is greater than 1

[@MathsNewSyllabusvarun]

so its wrong because your corrllelation coefficient lies between -1 to +1
