Hi, I understand that to test the significance of correlation between two PAIRED variables, the function, cor.test () can be used. However, in my case, I have tested the correlation (i.e., Correlation Coefficient, r) between two independent (i.e, different) variables, and now I wish to test for the statistical significance of the correlation. Could you please suggest how I should do that.
In a word, don't. If two random variables are independent then they
are necessarily (and obviously) uncorrelated.
Note that "independent" is not synonymous with "different".
cheers,
