Variables E and F have a covariance of 64, and variables A and B have a covariance of 635. How does the E and F relationship compare to the A and B relationship?
FIRST OF ALL , COVARIANCE MEASURES THE DIRECT REALTIONSHIP BETWEEN TWO RANDOM VARIABLES.
PROVIDED THAT , COV(A,B) = 635 , WHILE COV(E,F) = 64
NOW, IF THE VALUE OF COVARIANCE IS HIGH , THIS SHOWS THE STRONG RELATIONSHIP AMONG BETWEEN THE RANDOM VARIABLES
AND , IF THE VALUE OF COVARIANCE IS LOW , THIS SHOWS THE WEAK REALTIONSHIP BETWEEN RANDOM VARIABLES .
SO, RELATIONSHIP BETWEEN A AND B IS STRONGER THAN THE RELATIONSHIP BETWEEN E AND F BECAUSE THE COV(A,B) > COV(E,F)
I HOPE I WAS HELPFUL AND HAVE CLEARED YOUR DOUBTS.
