Coefficient of correlation between X and Y is 0.3. However on subsequent verification it was found that one pair (X = 10, Y = 6) was inaccurate and hence waived out. With the remaining 49 pairs of values, how is the original value of correlation coefficient affected? Solution. We are given, n = 50, = 10, = 6, σx = 3, σx = 2, rxy = 0.3 . We have,
