Calculate the correlation cofficient between X and Y and comment on their relationship. |
Answer» Solution : `bar(X)=(sumX)/(N)=(0)/(6)=(sumY)/(N)=(28)/(6)=4.67` Here, `sumxy=0, sumx^(2)=28, sumy^(2)=65.34` `R=(sumxy)/(sqrt(sumx^(2)xxsumy^(2)))=(0)/(sqrt(28xx65.34))=0` Correlation COEFFICIENT (r)=0 Since r=o , the two VARIABLES X and Y are uncorrelated. That is, there is no LINEAR relationship between X and Y. |
