Hi guys. I was wondering something. In my math class, we were analyzing how strong the data was, and there was an r and r^2 value. I know the significance of r, but what's the point of knowing the square of the r value?
Also, what's the use of square root? Like where does it help? I saw it one time in an equation in my chemistry class (I think Graham's law of effusion/diffusion), and of course, the Pythagorean theorem.
