1.	Calculate coefficient of correlation, given the following data :
Answer» Solution : `R=(sumxy)/(sqrt(sumx^(2)xxsumy^(2))),x=(X-bar(X)),y=(Y-bar(Y))` The table shows that , `sumxy=58,sumx^(2)=28,sumy^(2)=130` Substituting the values, we get `r=(58)/(sqrt(28xx130))=(58)/(sqrt(3,640))=(58)/(60.33)=+0.96` COEFFICIENT of Correlation (r)=+0.96. It is a SITUATION of high positive correlation.
