    It's crazy how easy and clear this video is considering how my professor uses a whole class explaining this and I had absolutely no clue while this only took me 4 minutes. Thank you so much!

    Make sure to have your diognastics turned on (press 2nd, 0, then scroll to D for diagnostics, then hit the diagnosticson button and then it will say done.) if you don't turn this on you will not be able to see your correlation coefficient (r) & (r^2) Great video by the way!
