Define correlation. In order to find the correlation coefficient between two variable X and Y from 13 pairs of observations, following calculation are made:
\(\sum X = 30\), \(\sum Y = 5\), \(\sum X^2 = 670\), \(\sum Y^2 = 285\), \(\sum XY = 334\)
On subsequent verification, it was found that the pair (11, 4) was copied wrongly. The correct being (10,14), find the correct value of correlation coefficient.
