Residuals and Linear Regression on a TI-83 

Thank you very much, this was so helpful.

This was helpful, but for some reason when i do all the same steps for finding y = ax + b it wont give me the r and r^2 options...

This video is really helpful! Thank you.

Amazing, ty

Yeah right now AP Statistics is kicking my butt but since I have RU-vid teachers like you I don't feel as stupid as I did before.

what do you press after you select calc tab option four to put down your L1 and L2?

Thanks
