Regression lines, Residual plots, and Correlation with TI-NSpire

I introduce the regression line and talk about some of it's key characteristics before showing you how to find it's equation with a TI-NSpire calculator.

I would just like to say thank you for giving detailed examples of using the Ti-Nspire. I bought this calculator in high school but now I'm in college everyone uses the Ti-83/84 so no one knows how to use this calculator. I've been struggling trying to use it for my Stats class I've been taking this summer but I've been watching all your videos on how to do EVERYTHING I need to know. So thank you for being so awesome and showing me how to use this calculator.

I think with consistent practice a month will be good. Their are tutorial videos on TI's website as well. I learned a little of calligraphy in middle school and then did signage at a grocery store for years and now do a little calligraphy as a hobby/small side jobs.

calligraphy much have been fun! :)

and thanks for the quick reply. I feel a bit more comfortable now. I just unboxed my CX CAS. I've been very impressed so far after just a few quick calculations.

Thanks for your help. :)

I'm glad you found it helpful...these comments reenforce the time that goes into making the videos and as always, I appreciate your support!

Hey
I live in India and I just ordered the TI Nspire CX CAS. This is pretty going to be my first graphing calculator. I was just wondering if operating it would be easy enough fo me to be comfortable with it in under a month. (I'm taking SAT Math Level 2 on Nov 3)

Thanks. (and I really do admire your handwriting :D)

[jsepn]

your handwriting is awesome. I wish mine were at least half as good as yours. :)

where's the fucking love button!!! THANKS! This really help me, I was going crazy looking for how to make the coefficient of correlation in the tinspire!!! :D

[Zarac]

Can you make a tutorial on how to do this on the ti nspire cx CAS? It seems just a bit different and I am having difficulty following my teachers instructions since she is using a ti 84 graphing calc to do this, not the CAS. You do such a good job with your tutorials!

Great tips....and consider that title corrected:D THANKS!!!
