- This video demonstrates how to generate the least squares regression line for a set of (x, y) data, how to make a scatter plot of the data with the line shown, and how to predict values of y using the regression line on the Ti-83/84 series graphing calculator.
Oh my goodness, thank you so much for your help. When it got to the point when my calculator did not show the r and r2 I thought I was lost, thank you so much for explaining how to put that on! Much more informative then my own teacher, and my textbook. Thank you!!
i don't know who you are, but you and these videos are a life saver to put it lightly
Oh Lord, thank God I found this! I have been able to reproduce in-classroom work at a fraction of the time from home... and, I have "learned more" in 10mins than I have in 4 weeks of class. !!!
Very clear...thank you for saying " let the calculator do the work". It's nice to hear an instructor encourage this!
I'm not a microprocessor
ive been to a tutor, the resource room at school, and to my teacher, but this video explained this 100 times better then all of them combined! THANK YOU!!!
THANK YOU!!!!!!!!!!! The thing about changing the settings was Sooooo Sooooo Helpful! I've been looking for why my calculator is missing the r for a long time! Exactly What I Needed! THANKS
This video is very helpful, one of the best I have found that not only gives good instruction with the calc. but also details how use. Thank you very much for posting :)
You literally just single-handedly saved my statistics grade.
thank you so much, you not only explained this better than any of the other tutorials on youtube, but u also went above and beyond what i expected!
i have my statistics final exam tomorrow, and you just SAVED MY LIFE
Honestly, this is 100000000 times more helpful than what my college teacher could have explained. RUclips is my Professor Now!!! :D
Thank you SO much for this video!! I am taking an online statistics class and it has absolutely been an adventure. I'm not great at math but do okay usually. Made it to week four doing everything by hand and now that its become so time consuming, I'm having to learn functions on the calculator and needless to say, have no clue what I'm doing. Thanks again for doing such a great job making this helpful video!
Great video. Clear, concise, what an awesome teacher!
Wanted to say thank you. My teacher does not cover this stuff very well and this helped alot!!!!
I do stats online, so I am teaching myself, which is very difficult. Thank you so much for making this crystal clear!!!
Thank you for mentioning how to have the calculator show "r" and "r^2" No one has been able to answer that question for me!
:D
you just saved me from a 4 hour (if not longer) attempt at reading the manual!!
Perfect explanation. I'm studying for the SAT Math II subject and this answered every question I had
Thank you
You explained this in a much more understandable format than my instructor
thank you so much, i wish all teachers were like you.
this is amazing!!!!!! you just saved me!! i swear i was about to give up lol i know how to do this on spss but now i was told to use my cal. and no one ever showed me how!!! so thank you so SO much
Thank you so much
When I go to put the linear regression function on my window it only shows up with the “X list Y list calculate” screen I can’t get it to where you’ve gotten it
You knew more than my teacher in school and you made a very good video.
you are awesome Mam.i am taking this class in an accelerated summer program(statistics) and you are so helpful in a time when i am swamped with 3 other classes also in accelerated format.
Thank you! I'm no longer on the verge of tears from not understanding how to do linear regressions and coefficients.
Thank you so much! My homework is so much easier now :) You are an amazing person!
awesome video!!!! walked me through my homework perfect. your smarter than my proffesor
OMG YOU ARE AMAZING, i have my college stats final tomorrow and this saved the day!
I make videos too. I like yours. Could you tell me what program you are using with the calculator and for your screen capture?
Excellent clear and concise instructions!!! THANK YOU VERY MUCH!!!!
@IntroStats Thankyou. I actually figured both out but then I couldn't convince the "check signers" I worked for to help me purchase either. Would of been awesome to have this for classes this year. Oh well. Very dissappointed, but love your work. Keep it up!
Wow !!!!! Thank you sooooo much. I am now ready for my test tomorrow:)!!!!
you've saved me from a mental breakdown, thank you billions
Best video on regression I might be able to pass my ap stats test now 😊
Thank you so much for your help!! I never would have gotten that stuff on my calculator on my own!!
Great video, clear and simple instructions. Good job
Thank you very much for the help! This will come in handy for my exam tomorrow!
Yeah, this video is pretty much awesome! Thank you for taking the time to make this. Very helpful.
Thank you. This was very helpful,
Question - I followed the steps exactly on my ti-83 and was unable to impose the least squares line on the plotted points.
Also when I attempted to store the Eq in Y1 it appeared on the command line but when I ran it again It displays ,"error invalid," When I try to recall the info in Y1 it is not stored.. Is there another adjustment I need to make on the calculator possibly?
I love you. For saving my IB 7 in Math.
You saved me ! I love you !!!!!!! From Portugal
thank you so much....this has saved my grade!!! i was totally lost...thanks again
Hey my calculator shows a different format when I press the Linear Regression option but when I press calculate I get the same answers like yours. The problem is when starting the scatter plot, when I go to VARS and select Y1 function it doesn't appear in the format like yours. Is there a setting I need to change?
THANK YOU SO MUCH! YOU ARE SO AWESOME! My teacher didn't teach this right, I was so confused! Dude! YOU'RE SO COOL! THANKSSSS! =)
This has been a huge help. Thank you so much.
im still unable to have the line. when i click on LinReg (ax=b) it takes me to a screen :
Xlist: L1
Ylist:L2
FreqList:
STore RegEQ
Calculate.
thanks a loooooooooot !!! i had a problem with r and r squared !!!
I apreciate it !!!
keep going !!!
For question c, if you were given y and x is being asked, what's the command?
Thank for the excellent demonstration. It was very clearly explained.
what about in the TI 82 i have a test on thursday i dont know how to show the correlation coeffient i know only how to find a an b but the correlation i have done all in vain
thx soo much i mas doing an algebra 2 review and didnt know how to do linear regression at all and this helped a ton!
Literally thank you sooo much ! You saved me for my test tomorrow ! I could not find r
Thank u so much!!! you saved my homework. I couldn't remember how to get r and r squared back.
Thank you very much for this video, the diagnosis on tip was very useful!
Thank you so much. You've saved me so much time.
You and me, dude. My math teacher only likes teaching his Honors math class and the MathTeam. He claims that the chapter is a "self teach" chapter. I'm sorry dude :( But glad the vid helped you. It did for me, too :)
Why isn't my calculator showing me the r and r2 when I do the LinReg?
Is there any possible way to get a sinusoidal regression?
I beleive that these videos are going to get me to pass math.
Not the teacher.
Thank you so much!!! The GDC makes me go crazy; so many functions! xS
extremely helpful, keep up the good work...u are amazing
the step you do at 5:03 doesn't work for me it just skips back to the screen where there is a xlist,ylist,freqlist,store reqeq and calculate - idk y
+Gloria Zeng In XList you want to put L1 in by pushing 2nd L1 (located above the #1), in in YList put in L2 by pushing 2nd L2. In the Store RegEQ you can store the Y1 that was mentioned in the video by pushing VARS, moving to the right to Y-Vars, going to Function, then you can highlight Y1 and push enter. I usually ignore the Freqlist.
Gloria Zeng
You don't have to do it, it works the same answer either way
Thank you for this great video. This was exactly what I needed.
There is a second linreg because in statistics the y intercept comes before the slope
You literally saveeeed me.. I LOVE YOUUUU
Don't you usually use linear regression function for a+bx not ax+b?
An easier way to get "stat diagnostics" on/off option, is to go to the calculator "mode", ("mode" button is between the "2nd and "Del" keys), and near the bottom, just before the "set clock," you'll see options to turn "stats diagnostics", and "stat wizard" on or off.
TOOK ONE HOUR TO EXPLAIN THIS IN CLASS TODAY, WHAT ARE WE PAYING FOR
Thank you SO much! You’re a life saver!
@IntroStats I did find this after running some searches today one emulator called wabbit. It says it works on the Apple OS and I tried posting the link but I guess you tube won't let you post links. Let me know if you try it and if it works well.
how do you get a calculator in your computer?
helps a lot. Now i don't have to wait until I get to a computer with excel
Awesome video!!!! I love ti!
Fantastic guide it greatly helped me!
Awesome, you are a savior.
Thank you so much!!! You just made my life soooo much easier! :)
Hey for some reason when I calculate LinReg it only shows the equation. It doesn't give me r or r^2. Anyone know whats up?
You have to turn DiagnosticOn. Go to Catalog (2nd 0), then press the x^-1 button as a shortcut to get to the Ds, then select DiagnosticOn and press enter, and enter again until it says Done. Now r and r^2 will show up with you do a LinReg.
Yes - she explains how to fix it in the video.
A LIFE SAVER!!!!
AWESOME! very well explained, made it so easy THANKS
sooooooo HELPFUL...thank you!
Very helpful. Thank you very much.
@cheatsisbrown I'm trying desperately to achieve a 7 for my math project! Well done!
My calc is saying error invalid dim! please help!
THANK YOU! You just help me get this
Great post!!! Thanks so much.
Thank you! Very good video!
This was so helpful!!!
@ProfessorRosever There's a nice 83+ emulator, a free one, that would work, too. But it doesn't have those nice graph and list views. It's called Virtual Ti.
If only they worked on a Mac I'd probably do more videos, instead I have to borrow and return a school laptop, kind of a bother.
Thank you! That was really helpful. 😃👍
Thanks a looooot! Excelent way to explain it! :))))
Great Teaching!
well thanks for letting me keep my hair and not have to rip it out of my head in frustration
Your the best!
u save me totally u save me!
this was awesome!! tytyty
Thank you, this was helpful.
you're da real mvp :')
Why is it telling me error mismatch
Thank you very much, helped a lot! :)
