The following results were obtained in a study of correlation coefficient between two variables X and Y: n=50, x = 10, 0̟=3; y =6, y= O, = 2; r = 0.3. xy !! However, on subsequent verification it was found that one value of X = 10 and one value of Y = 6 were inaccurate and hence weedėd out. With the remaining values how is the original value of correlation çoefficient affected.
