Pre-Calculus - Find the linear regression line using the TI-83/84 calculator
HTML-код
- Опубликовано: 22 авг 2024
- 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 💀
😅😅😅
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!
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!
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
Thanks
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 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
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.
what are you doing now?

Helpful! Who here in 2018 lmao literally no one
Me lol
MEEEEEE
Kyra S yooooooo I’m here and hating it, vid was helpful tho
..
bruh i'm here in 2019
BAHAH
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!
Glad I could help you out. Keep up the good work. :^D
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.
Literally the best tutorial I’ve ever watched.
Thank you I’m studying last minute for the Algebra regents this helped fr 😭
THIS IS THE BEST THING TO EVER HAPPEN TO MY MATH GRADE!!!!!!!
You explained it MUCH better than my math teacher did! :)
Thank the Lord for ur soul, u saved my test grade
getting ready for a vet exam and this video just saved me for chemistry kinetics... life savior!
This was so helpful! Thank you for simplifying this for me!!
Was sick for 3 days and had no idea what was going on. Came here, now I know what to do.
you saved my life, and have no more issues with my calc thank to u
You are literally the best. I have a test tomorrow and I needed this so much. Literally an absolute W.
wow!!! 2020, and I found this..... thank you MySecretMathTutor
Wow, thank you! That all seemed complicated at first, but you walked us through it quite nicely.
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!! My professor didn't explain this very well and I have an exam today. Perfect explanation!!
Thank you so much, this helped me figure out a lot of things.
Loved the help but try getting a new camera for higher quality so I can see the calculator better
Thanks a ton man, i can feel my grades getting higher
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.
I didn't even know about the catalog thing that is tricky. Thank you so much!!
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
Thank you soooooo much!!!!!!! my teacher only taught us for the TI calc on the computer you are definitely a life saver!!!
Thanks so much for posting this- you helped me pass stats class!
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” 😅
Letticia Delgado i our a comma on mine and it’s not working 😭😭
😩THIS WAS SOOOOO HELPFUL!!! Thank you!!🤗🤗
This is an awesome video and well explained. I forgot all of it but I got it back on 10 min. thank you....
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)
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.
not to mention I was a week behind on homework.
Thanks!!! I used this video to find out how to get the r1 and r2 thing!! Very helpful and informative video!!!!
Thanks for the help, answered everything I needed to know!
Using a Ti-84 Plus, I get an r value of .934. Any thoughts on why this could be?
Thank you so much, spend hour just try to figure out why mine does not show reg^2.
Thank you so much! Diagnostics on omg, so simple. You are a life-saver!!
Thank you SOSOSOSOSOSOSO much! I am doing a Linear Regression project from my Algebra 1 class and this helped me a ton!
This explanation worked even though I was using an fx-9860GII, super clear and helpful, actual math teacher couldnt come close.
Hmmm, I don't have that calculator yet. Time to put in an order. :^D
Buttons obviously not the same but just actually being told where I was supposed to go was a help
thanks a lot, i was kinda stuck. thanks to the video i can continue with what i'm doing
Thanks you so much I really needed to get R back in and I couldn't remember how to.
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
Thank you, i just bought a T-84 and needed help. ( switched from a casio )
Thank you so much for doing this video and going slowly. Just thank you very much, great video!
Thanks! Just need to memorize these steps now and I’ll be set! 👍🏼
this is the best video ever thanks so much
This video nailed it! Where are my "r" values????? Watch video.... There they ARE!!!!!
Thanks a lot, wish my teacher explained stuff this well.
Thanks dude. Never covered this in class. It's straight forward and to the point!!! Thanks again.
Thank you so much! My math teacher didn't explain this nearly as well as you did.
Thank you SOOO much for posting this!! Super helpful video!!!
you just saved my life
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
this is very helpful especially now. Who here in 2020?
I'm still here, so that's a good thing. :^D
Thanks you are my savior
Thank you! - a bachelors' student
Thank you! You just saved me from failing my quiz tomorrow
Who here in 2019?
Me
I'm still here. :^D
I don't think math or TI calculators will be updated any time soon lol
So glad I found this video, I was going crazy. Glad to know what that "catalog" button does now, 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.
Have you seen the new HP Prime color graphing calculator that is coming out later this year? You can find it on RUclips. It looks like TI & Casio have some major competition against their TI Nspire CX CAS & Casio CP400.
hey thanks, was absent a day, now all caught up
this video is great except he uses the linereg (ax+b) instead of #8 which is linereg (a+bx) which does make a difference
Also works for a TI-82 STATS
Good to know. Thanks! :^D
Very, very helpful video. Thank you very much
What would I set my Frequency to in the calculator though? Should it be List 1 or List 2?
thank you for the help on the diagnostics on thingy :)
thank you, my grades and I appreciate your video
Super helpful, thanks! 2019, try me lol.
Great video, very helpful!!!!
Yeah, same here... who knew the diag was off. sheesh. Many thanks OP!
Thanks, this was really helpful!
I appreciate your job.
Thanks man you're a life saver!
you saved my life!!! thank you!!
YOU R THE BEST !!! THANK U
Thank you!! This video was a BIG help!!
this was very helpful thank you
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
Payed 500 for a class to teach me this and you tought me for free
Wow! YOU ARE THE MAN! Thank you so so sooo much!
what a life saver
Thank God for you
That was great and helpful.Thanks for uploading.
Thank you SO MUCHH!!!!! SOOOO helpful!
Thanks! you are my hero!
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?
@Fluffylovesyou191
Make sure you selected diagnostic on and NOT diagnostic off.
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?
this saved my grade
My teacher makes us do more steps then this and now that I see how easy this is it makes me think that I’m doing something wrong 😆
Helped a lot, forgot how to do this in my 8th grade algebra class lol
