Thank you!
******************************
This video shows you how to find the Least Squares Regression Line (equation form and graph) on the TI 83/84 Calculator. I also show you how to plot the Scatter Plot with the line as well.
I know this is old but tysm for making a video that explains this 10 times better than my 80 year old algebra teacher
Brooo same
Being able to do this on the calculator saved me precious time! I cannot thank you enough for this, my statistics professor does not spend any time instructing us on how to use the required calculator for the class, and without videos like these I would not pass this class! So thank you again, just know these videos are extremely useful for people like me.
I have a teacher that explains things well but i’m a dumbass and this video has allowed me to understand the concept a lot better. Thanks!
If I watched this video sooner, I wouldn't have to put unnecessary amounts of hours trying to figure it out without knowing how simple it really is. Thank you for putting this into such easy and straightforward explanations!
Thanks for explaining this better than my teacher. I actually understand my homework. I could not have done it without with you.
This helped clear a lot of confusion I had regarding my homework questions. Thank you!!
omg you helped me so much!!! :) thank you! because of you I was able to finally get my homework done! Hallelujah!!! :)
THANK YOU. My A.P stats teacher is teaching the class for the first time in her life, and everyone is dropping it (from 24 students to 14). Shes trying to teach us, but this is so much clearer than her method!
thank you so much, you are a life saver. i don't know why in the hell i can't get this information straight from my pearson course.
because Pearson is the Devil
Studying for a test so this was very helpful thanks!
I understand now!! You explained it very quickly and easily. Thank you so much!!
Thanks a lot! My teacher doesn't even know how to use our calculators correctly so your video really helped me understand better
Very, very helpful. Thanks so much for making this.
I saw a problem very similar to this on the FE Civil Exam. Unfortunately I didn't see this video until after I took the exam. Fortunately, I eventually passed the exam on my third attempt.
Incredibly helpful. Thank you so much!
I don't know what the hell I am doing but this video helped me do what I needed to do hahaha
Saved me on the night of an exam THANK YOUUU!!!!!
This video was soooooo helpful. Thank you!!!! Looking forward to more of your videos!!!(:
You’re a legend I had no idea I had to turn on diagnostics it wasn’t showing me r and r^2 it was driving me crazy
thank you for the video its old but really helped alot and saved alot of paper work
Glad it helped!
Thanks a lot! You explained it really good! Great video!!
Thanks very much for this. It really helped me to understand how to do this better!!!
The question sample that you used, was the exact same question I was stuck on, different values of course. Thanks so much for explaining how to do it with the graphing calculator!!! Saved me so much time :)
Thank you so much! Please, if possible post more videos! Very helpful :)
This is super helpful, thanks for posting!
OMG Thanks really broke it down so I can understand it
Thanks so much! Quick and simple steps. Thanks!
Thank you, this was so helpful.
Yes, thank you SO MUCH!
Thanks you so much! Very helpful 👏🏽
Thanks. Catalog/Diagnostics cured my problems
good paced of explanation; thanks
Awesome video, thank you very much
thank you! I appreciate you
Thank You, very helpful!
THANK YOU
thanks a lot this was extremely helpful
thanks soo much! Much needed!
actually so helpful
Oh my goodness thank you you're the best
Thanks for the help!
Thank you so much for this amazing and simple video. This is going to help on my test
Thank you !!!!!
You are amazing
So helpful, thank you thank you thank you
very helpful....thank you!
Two words: Thank you!!
Very helpful!!
What a savior
Thanks dude
your amazing
Life saver!!
awesome bro
Thank you.
Thank you so much...
OMG So Helpful!!
Thank you!
i love you man
thank you!!!
Thank you so much
to graph the line instantly, you can go to Vars, Y-Vars, Function... and add Y1 to the end of your LinReg
LinReg(a+bx) L1,L2,Y1
thanks !
thanks for safe my life :) There was no way to do it for typing in there I don't know why
Very helpful. Questions like this on AP Stats test or not?
This just saved my life. Not joking 😁😁😁😂😂
God send
Thanks!
I have diagnostics on but when I enter lists, L1 and L2, use LIN REG all I get is the linear equation, no R^2 and no R. I'm using the TI 84; I'm not entering in the Y intercept and the slope to get the line, it is automatic. At the #4 LIN REG: Xlist:L1, YList:L2, freqlist: blank; Store RegEQ:Y1. Any thoughts?
thank you, Anne
Check again on the diagnostics. Make sure to actually click - diagnostics on. So it shows on screen and says done.
when i do this, i can only ever get to the point where i've gone into stat, calc, then the option that i need (option 4 in the video, option 8 for me, but i have this problem no matter which one i use). after that, instead of being able to just hit enter like in the video, if i hit enter it says error because i'm missing information. i have to put in "Xlist:" (i've been putting L1 here), "Ylist:" (i've been putting L2 here), then "FreqList:" and "Store RegEQ:" (i don't know what to put for either of these), and THEN hit calculate. anyone have any idea what to put there or if i'm doing it wrong?
so if the question on my homework is asking me to "state the least squares regression line" what exactly do i put?
Can you get the calculator to give the y-hat number?
when finding the least squares regression line, do you always use (y=ax+b)????
Manuel Estrada-Felix III yes. For a linear regression. It’s a line.
When i hit enter it takes me down a line where youre entering y plot... why?
Oreo - I can't reply to your comment. The least regression line is the equation that you find. You need to put it together. y = ax+b
instead of little a and b in vars statistic and hit 1)RegEQ
How do you find the residual?
when i go down to 4: at 0:54 time stamp my calculator says Error: Invalid DIM :(
T ღ check that a plot is not on. Hit Y=. The plots at the top should not be highlighted. Also check your window. Hit WINDIW and click standard. Make sure L1 and L2 are empty. Then start problem. You can reset machine if problem persists. See how to reset TI calculator video.
I followed the steps and only the scatterplot is displayed...the linear regression line is not displayed on the scatterplot.
+Zachary Flury What do you have in the y= area? Did you follow those end steps at 2:23? Have to use the a and b in VARS STAT EQ.
AP Exam thursday 🙍♂️
bruh
For some reason, my b is always wrong but the A is right. I'm having trouble
lol i have a test due in like 3 hours
it is 5 am rn save me
Did the same steps, but sadly my line never shows up :/
click ZOOM FIT
this got blurry 4 me
I'm doing this in 8 grade cuh
You look too good to me to understand because go to fast. I cannot post a video every second and write down notes in order to understand how to do my exercise so please I suggest you to really be helpful by talking slower and showing slower how to press the buttons on the calculator. That way you’re gonna have more viewers.
Hirma Guma there is a pause button. Most people do not like slow videos. Just watch it first. Then go through it again and pause it after I tell you to do something. Don’t try and do it the first time you watch the video. You should try learning what I’m teaching, not just copy what I do. Understand why. Just watch it first. No notes or anything. Then watch it again, this time pausing and rewinding when necessary. And I’m not in it for the views. Although, I do have 2+ million views on the channel.
