    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!

    I'm in college and I am taking statistics. Sometimes my teacher goes to fast to follow all the steps. I was doing my Homework when I got stuck on this question, so this video helped me a lot. I subscribed ^_^ I like your videos, they will help me a lot this semester.

      Its hard to say. Texas Instruments have been making the Ti-84 for some time now and they have been making improvements. One thing I noticed was the use of "pretty print." I like to turn this off, but if you check the setting in your calculator, you'll probably find it. This helps display things like powers and fractions more accurately. :^D
