computer operator white calculating the coefficient between two variates x and y for 25 pairs of observations obtained the following constants:
n=25,?X=125,?X^2=650 ,?Y=100,?Y^2=460; ,?XY=508
It was however later discovered at the time of checking that he had copied down two pairs as (6, 14) and (8,6) while the correct pairs were (8,12) and (6,8). Obtain the correct value of the correlation coefficient.
