Linear Regression Models using a Graphing calculator 

you taught me this better in 8 minutes than my teacher did in two days.

OH MY GOSH. THANK YOU SO MUCH FOR THE UPLOADING THIS! It really helped me a lot at my tests

Thank you, from a grown man struggling with calc1. I just knew there would be a way in my trusty 9860Gii. What a powerful, powerful tool this is. A simply 10 point line takes my calv over 2 seconds to find regression. Must be a lot of math required, which would explain why there is no answer to the question "can this be done on paper".. in sorry to say there are a few things (regression being one) that simply are not feasible by hand. Matrices >3x3 being another.

Thank you, thank you, thank you! My teacher really sucks at explaining (he's smart but not smart at teaching unfortunately). I've been practicing this exact problem to see if I get the hang of it and I do :) Thank you so much, again!!

I just did an at home precalc test. THIS HELPED ME SO MUCH! THANK YOU! Seriously, thank you!!!!

Soooo much better than my math teacher

@MrsMcPhersonTHS, Thanks so much, at first i thought i would be stuck trying to do Linear regression on excel but even with my TI-83 Plus model; this tutorial was a breeze to understand!!!

thank you so much; you are very articulate!!!!!!!!!!!!!!!!!!!!!

excellent! step by step.

This video was very helpful ! thank you !

Extremely helpful tysm!

It helps me a lot! thanks

Thank u sooo much this really helped me out

THANK YOU !!

thank you that was an amazing video it was real help. :)

My pharmacology teacher asked me how to put the unknown x values into my fancy TI-84 after I calculated the regression equation, and I didn't have a clue. Made me feel like a total dumbass. Next time I'll watch your videos first!!

thank you a lot a lot a lot very helpful

Thank you so much

The Linear Regression part in Stat>Calc does not work for me.

shoutout to mrs.horn not explaining this so thanks

How to find unrounded models? If someone knows plz help me Thank you
