Question

1 From the following data calculate co-efficient of correlation :
X = 0.85 Y and Y = 0.89 X
​

Answer 1

Answer:

x^2* 0.89 = y^2*0.85

here is the answer

Answer 2

Given : X = 0.85 Y and Y = 0.89 X​

To Find :  co-efficient of correlation

Solution:

X = 0.85 Y

Comparing with

$X=a + b_{XY}Y$

=> $b_{XY}=0.85$  

Y = 0.89 X​

Comparing with

$Y=a + b_{YX}X$

=> $b_{YX}=0.89$  

co-efficient of correlation  = $\sqrt{(b_{XY})(b_{YX})}$

=> co-efficient of correlation  = √(0.85)(0.89)

=> co-efficient of correlation  = √0.7565

=>  co-efficient of correlation  = 0.8698

=>  co-efficient of correlation  = 0.87
