1.	From the following data, compute the coefficient of correlation between X and Y series. Summation of product of deviations of X and Y series from their respective arithmetic mean =41
Answer» Solution :We are given `N=6,bar(X)=350,bar(Y)=138,sumx^(2)=19,sumy^(2)=94,sumxy=41` `R=(sumxy)/(sqrt(sumx^(2)xxsumy^(2)))` Substituting the values, we get `r=(41)/(sqrt(19xx94))=(41)/(sqrt(1,786)=(41)/(sqrt(42.26)=0.97` Coefficient of CORRELATION (r)=+0.97
