If for two variable x and y ,the covariance,variance of x and variance of y are 40,16 and 256 respectively, what is the value of the correlation coefficient?
Verified Answer
If for two variable x and y ,the covariance,variance of x and variance...
We know that
r x sdx x sdy = cov( x,y )
Hence,
r x 40 x 16 = 256
r x 20 x 8 = 256
 160r= 256
 160/256=r
 0.625 = r
