Sir the doubt is –
Which of the following is NOT a feasible value for correlation coefficient.
A. +1.2
B. +0.6
C. 0
D. -0.9Sir the answer as per the book is A. But how can 1.2 not be a feasible correlation coefficient as the closer it is to 1 the better it is.
My answer was C. Zero.
Because if its zero then there is no correlation .
Can u please explain why it is +1.2 and why not the others ?The coefficient of correlation will always lie between -1 and + 1.
It is impossible for it to be below -1 and impossible for it to be above + 1
The question is not asking what is a ‘good’ value – it is asking what is a possible value. 0 is a possible value (even though it means there is no correlation).
I suggest that you watch my free lectures on this.
The lectures are a complete free course for Paper F2 and cover everything needed to be able to pass the exam well.
I do watch your videos Sir. Thank you nevertheless for clarifying this doubt as they are bound to pop up every now and then 🙁
