Uh, it's the same, whatever answer you'll get, R, you'll get. But here, what happened? One of the values negative value have. So, whenever negative values are there, we can't go for square roots, we know already, right? Only positive values we can do.
So, negative values we can't. So, I we wrote here, so that is your complex number. So, there is no correlation coefficient. Generally, if you get positive values, go for the formula, substitute, and get the answer. Here, because negative value is there, write it down as it's a complex. So, we can't get the correlation coefficient. So, that is your final
