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

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

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!!!!!

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!

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!

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

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.

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

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 :/

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!

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.

I literally have my quiz tomorrow and found no any clue anywhere else about this topic and really feeling so relaxed after this video. Thank you so much and this really means a lot. Best explanation🔥

Helpful! Who here in 2018 lmao literally no one

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

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

Literally the best tutorial I’ve ever watched.

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

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

Thank the Lord for ur soul, u saved my test grade

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

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

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

You are literally the best. I have a test tomorrow and I needed this so much. Literally an absolute W.

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

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

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

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

this was so awesome my pre cal teacher sucks and i finally understood how to do this!!!

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

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

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

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

I did everything I even turned the diagnostics on but I keep getting something that looks like this : ERR: SYNTAX 1: QUIT 2: GOTO please help Edit: hehe never mind I forgot to put the comma” 😅

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

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

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.

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

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

Thank you so much, spend hour just try to figure out why mine does not show reg^2.

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

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

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

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)

😩THIS WAS SOOOOO HELPFUL!!! Thank you!!🤗🤗

Thanks you so much I really needed to get R back in and I couldn't remember how to.

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.

Thanks for the help, answered everything I needed to know!

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

Thanks! Just need to memorize these steps now and I’ll be set! 👍🏼

thanks a lot, i was kinda stuck. thanks to the video i can continue with what i'm doing

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

Thank you, i just bought a T-84 and needed help. ( switched from a casio )

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

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

Thanks a lot, wish my teacher explained stuff this well.

Thank you so much for doing this video and going slowly. Just thank you very much, great video!

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

Very, very helpful video. Thank you very much

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

this is the best video ever thanks so much

What would I set my Frequency to in the calculator though? Should it be List 1 or List 2?

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

Thank you! - a bachelors' student

So glad I found this video, I was going crazy. Glad to know what that "catalog" button does now, lol.

hey thanks, was absent a day, now all caught up

Thanks you are my savior

thank you, my grades and I appreciate your video

thank you for the help on the diagnostics on thingy :)

Thanks dude. Never covered this in class. It's straight forward and to the point!!! Thanks again.

you just saved my life

this is very helpful especially now. Who here in 2020?

Thanks, this was really helpful!

I appreciate your job.

I was just about to ask the same thing but your the man!!! How do I get the line to show up on the graph though? I have the data points but the regression line doesn't show up

My slope and y-intercept values don't seem to fit my plot very well, and I also can't get a line going through the scatter plot. Can you help me?

this was very helpful thank you

Great video, very helpful!!!!

Super helpful, thanks! 2019, try me lol.

That was great and helpful.Thanks for uploading.

you saved my life!!! thank you!!

Thank you!! This video was a BIG help!!

Thanks! you are my hero!

I enter the information like you said to do and I get the the part where I have the LingReg (ax+b) L1L2 so on and so forth and I keep getting and Err: Syntax 1:Quit 2:Goto. I don't get anything else.

YOU R THE BEST !!! THANK U

what a life saver

Helped a lot, forgot how to do this in my 8th grade algebra class lol

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.

Big thanks to you sir! 😃

I keep getting even numbers in the results, do I have to turn on anything so that doesn't happen?

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

I was trying this out but couldn't get the r. I only get a and b. Do you know how i can fix this?

How do i find the regresion line of x on y and use it to predict ?

Thats the best math video ever thankss!!!

very helpful video, loved it. just a question though. why does it give a different value for a and b when you input the lists the other way around (L2, L1)? is it due to the independence of the variable?

Thank you SO MUCHH!!!!! SOOOO helpful!

My numbers are slightly off, how do I fix this?

This video nailed it! Where are my "r" values????? Watch video.... There they ARE!!!!!

Thanks for the video, but when i press the LinReg(ax+b) button, I get the a and b values, but not the regression values. did I do something wrong? are my settings messed up? I did it on a TI-84 Plus Silver Edition, does that make a difference?

Yeah, same here... who knew the diag was off. sheesh. Many thanks OP!

Also works for a TI-82 STATS

Thanks man you're a life saver!
