I am using the formula to determine the correlation coefficient r, why am I getting an i in my answer
You probably need to include more information. We do not have a crystal ball :)
I have a crystal ball –compliments of Morgan Tud. I’ve not yet figured out the mystery to make it work. However, I do see very pretty things in the orb –usually my garden flowers or my own face. Sometimes it’s both at the same time –it’s really beautiful then.
