In two sets of variables X and Y with 50 observations each, the following data were observed X = 10, SD of x = 3, y =6 , SD of x = 2 Co efficient correlation between X and Y is 0.3 . however on subsequent verification it was found that one value of X (=10) were in accurate and hence weeded out. With remaining 49 pairs of values, how is the original value of correlation coefficient affected.
