Pre-Calculus - Find the linear regression line using the TI-83/84 calculator

This video shows how to find the linear regression line using either a TI-83 or 84 calculator. Remember that if you do not see r squared or r, then you need to turn diagnostics on. For more videos visit www.mysecretmat...

You just saved so many people's grades. Thank you dude, I'll probably be back in a week 💀

😅😅😅

[@andygallegos9305]

omg you have no idea how grateful I feel. I literally owe you my life. I sorta wanna cry. This helped so much. Thank you!!!!!

[@augustsunshine2860]

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!

[@ameerap.5604]

Thank you soo much for this comment. I was sitting here wondering why I didn't the r and r squared. You saved me so much time!

[@susu9659]

Thank you so much for this comment, you saved me a lot of last min exam stress

Saved my ass ty

He does say this in the vid, but still very helpful comment, thx

[@JamalYoung]

Thanks

[@nei3488]

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!

[@divingmaster818]

So incredibly simple, incredibly clear, and well explained. Helped me so much on my finals thanks!

[@Anna-yd9wz]

I can't tell you how grateful I am that you posted a video so simple and perfect! Taking statistics online with no 'one on one' classes is hard enough and this made it just a little easier

[@lotusflower5180]

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.

[@katelyngale5310]

Thank you SOOOO much!! I'm in Pre-calc and I couldn't figure out for the life of me why my calculator wouldn't graph it. I figured it out with your video that I needed to turn on diagnostics!! You're a life-saver!

[@MySecretMathTutor]

Glad I could help you out. Keep up the good work. :^D

[@avaa_danielss]

THANK YOU SO MUCH FOR THIS this video was perfect and you did everything a great math teacher should do! I wish my teacher actually explained stuff instead of giving us a worksheet and telling us to figure out regression by ourselves at home :/

[@ErlingGrey]

Literally the best tutorial I’ve ever watched.

getting ready for a vet exam and this video just saved me for chemistry kinetics... life savior!

THIS IS THE BEST THING TO EVER HAPPEN TO MY MATH GRADE!!!!!!!

[@Asstickler2000]

Thank you I’m studying last minute for the Algebra regents this helped fr 😭

[@zurcasi]

Thanks for this, my teacher that claims to be an expert with these calculators didn't even teach us, let alone how to do this.

[@kyras1123]

Helpful! Who here in 2018 lmao literally no one

you saved my life, and have no more issues with my calc thank to u

[@sophiahullinger5590]

This was so helpful! Thank you for simplifying this for me!!

You explained it MUCH better than my math teacher did! :)

[@Madzcon]

Thank you so much!! My professor didn't explain this very well and I have an exam today. Perfect explanation!!

[@peaceegwuonwu9632]

wow!!! 2020, and I found this..... thank you MySecretMathTutor

[@annikaclark2873]

I don't usually comment on videos, but this was so helpful! I'll probably check out your videos first from now on. Thanks!

[@drewsharkey8016]

Was sick for 3 days and had no idea what was going on. Came here, now I know what to do.

[@shiloh7105]

Wow, thank you! That all seemed complicated at first, but you walked us through it quite nicely.

[@SatvikSharmaJedi]

Thank you so much, this helped me figure out a lot of things.

[@fentanylmusic1462]

Thank you soooooo much!!!!!!! my teacher only taught us for the TI calc on the computer you are definitely a life saver!!!

[@Animeandcoffee8199]

I made a 35 on my math test because I didn't know how to do this, now I'm doing the corrections with this video. Thank you.

[@dwmh55]

Great - I'm a maths teacher preparing for this lesson.
Stat diagnostics on was precisely my problem.
Note the short cut is that Stat diagnostics can be turned on via mode button (hen 2nd page)

[@jaymiranda2008]

Thank you so much for the helpful walkthrough! After every class session I always look for one of your videos to follow up so that I can better understand the material

[@javiersimmons316]

Thanks a ton man, i can feel my grades getting higher

[@simonriley4375]

I didn't even know about the catalog thing that is tricky. Thank you so much!!

[@gomezaddams42]

Thank you SOSOSOSOSOSOSO much! I am doing a Linear Regression project from my Algebra 1 class and this helped me a ton!

[@chitwinsantun7376]

This is an awesome video and well explained. I forgot all of it but I got it back on 10 min. thank you....

[@tallmanquinton2931]

Loved the help but try getting a new camera for higher quality so I can see the calculator better

[@crazydaisypinecone]

Thanks so much for posting this- you helped me pass stats class!

[@starruler3258]

thank you so much! I had looked up other directions and they were just confusing me. I had homework due the next day at they end of the year for the last day of math and I had no idea how to do this. THANK YOU SO MUCH! I gave your video a like.

[@starruler3258]

not to mention I was a week behind on homework.

[@jamiejamie9549]

This explanation worked even though I was using an fx-9860GII, super clear and helpful, actual math teacher couldnt come close.

[@MySecretMathTutor]

Hmmm, I don't have that calculator yet. Time to put in an order. :^D

[@jamiejamie9549]

Buttons obviously not the same but just actually being told where I was supposed to go was a help

[@composingmaddie]

Thank you so much! Diagnostics on omg, so simple. You are a life-saver!!

[@jaiboibiscuit2363]

Thanks, this was very well explained and a huge help! :)
I can now relax about my assessed investigation tomorrow! I always struggle with graphics calc stuff

Thanks!!! I used this video to find out how to get the r1 and r2 thing!! Very helpful and informative video!!!!

[@letticiadelgado9865]

I did everything I even turned the diagnostics on but I keep getting something that looks like this :

you just saved my life

[@horizontaljumper1991]

Using a Ti-84 Plus, I get an r value of .934. Any thoughts on why this could be?

[@karenacox4311]

Thank you SOOO much for posting this!! Super helpful video!!!

[@krymykin]

Thank you so much! My math teacher didn't explain this nearly as well as you did.

Have you seen the new HP Prime color graphing calculator that is coming out later this year? You can find it on UA-cam. It looks like TI & Casio have some major competition against their TI Nspire CX CAS & Casio CP400.

[@Semperfi870]

Thanks man you're a life saver!

how do i make the graph so that the line can only be in the top right quadrant? or in other words, the line is only positive

Big thanks to you sir! 😃

[@ArsenGTS]

You are the best!!!

[@dwmh55]

And the joke is on me.
Prepared for my lesson and knew exactly what to do with both the TI84 and the Casio only to find the two students with TIs had an 83 and an old OS on an 84. I needed an urgent rush to the internet during the break to rediscover your way or turning Stats Diagnostics on.

Wow! YOU ARE THE MAN! Thank you so so sooo much!

Make sure you selected diagnostic on and NOT diagnostic off.

Thank you! You just saved me from failing my quiz tomorrow

[@cherishpressley5729]

this video is great except he uses the linereg (ax+b) instead of #8 which is linereg (a+bx) which does make a difference
