Thank you..... sooooooo much! most of these vids just show one part without another, but this one explains every single step involved! thanks so much again
When using LinReg, after you enter the two lists, add another comma followed by Y1, and the equation will be placed into Y=. To add Y1, go to Vars > Y Vars > Function, and then choose Y1.
I watched many videos about scatter plotting. On all of them I got lost after Zoom 9. Your video finally made it clear to me. I know have it written down as 9 steps on the note card that I will be allowed to use for my exam. Thank you so much!
You did great I am trying to past stats online, no one has shown me how to do this TI-84 calculator, thank you for helping me. at least if I know how to use and place the linear correct, I can learn stats. Thank you
I'm on yt because my text is a bit weak explaining correlations and I didn't know how to do them in my TI-84. This was so helpful. Not just the steps, but also the explanation that the coefficient of variation is the percent of variability in the y value that can be accounted for in the x variable. It seems like the unifying concept, but my book didn't touch on it.
@9:00 - DO NOT manually type in the data, unless your teacher is perfectly happy for a rounded version. If you want the exact values to be plugged in automatically, so that you get exact answers, type in the 'LinReg(...)' command, then 'L1,L2,' At the end, you want a third argument: where to store the function. Go to (next to 'Clear') VARS > Y-VARS > Function... > 1: Y1. Hit Enter after the three arguments, and you will not need to plug in the equation manually.
+caleb williams By the way I was using cubic reg, I suppose that makes a difference? still, I really need to know why it isn't working and how to solve it, please help!
we learned this in class, but i have a problem that you may be able to help me with. i have entered all data up until this point. when i am in the "y=" and go to y-vars>funtion, only "y1, y2, etc." appear rather than the actual equation for y1, y2, etc. as it did in the example our professor gave us. the problem is when i would enter just "y..." in my y= menu, then try to do anything, it would tell me the error lies in the lack of a equation after "y=Y1" is there any way to remedy this?
You can turn terminating decimals into fractions on the calculator by first entering the number, then press the MATH button, then press 1:Frac. Using the fractions, you can rewrite your regression equation so the coefficients are in fractional forrm.
**I meant don't manually type the EQUATION into 'Y1'.** On the new TI-84 operating system, it gives you a menu where you fill in the blanks with L1, L2 (default), and you need to type Y1 using the VARS > Y-VARS > Function... > 1: Y1 menus in order to automatically get the equation put into Y1 for you.
Short and simple. You're a great gem of a teacher. Thank you for posting.
That was amazingly detailed. Thank you so much! You answered all the questions and resolved all the issues I was having with trying to do this.

Great video, everything I’ve been looking for
Lifesaver!!!! Thank you!
Awesome! I was able to follow the step by step directions. This is very detailed! Thanks so much. You saved from forking out a fortune to my tutor.

I was wondering why it didn't show r and r squared, but now I know, so thank you so much!

Extremely helpful and very descriptive! Really easy to follow. Thank you so much!
I have a mid term tomorrow and this saved me, thank you so much
Really helpful! Thank you! Nice recording, step by step guidance and nice voice, too!

I feel so relieved. Thank you, one hundred times.
Thank you so much!! You really helped me figure this out!!

thank you for the video, the way you explained made so much sense:)
Thank you for your help. Nice Video
Thank you, very concise! Tremendous help.
Thanks for your help! this is fantastic! Love love
Kindest regards Sarah and Chloe (your dearest friends)
That's exactly what I needed!
This is awesome! this'll help me with my quiz BIG TIME!!
Wow , this makes perfect sense , thank you !!!!
caleb williams- did you get that error figured out? I have the same problem and am not finding the solution anywhere
Thanks, this answered a problem I could not solve eg the non appearance of the correlation coefficient
I have followed the directions and it reads Error. Am I doing something wrong?
My hero! LOL thanks so much!!

SO HELPFUL!!
Im getting some different values on my Ti-84 Plus. I got 15 for a, 202 for b and r value= .725. Any thoughts on why this is happening?
I would suggest double-checking that the numbers in your two lists have the correct values.
Clear your calculator
Thank you!!!!!
Thank you so much!!!
Really helpful!! Thanks
I followed your directions, and I got
ERR: SYNTAX
1: Quit
2: Goto
do you know how I can get it to graph?

I can't seem to get the r and r square on my calculator. It only shows the a and b and the slope intersect form. Anyone help?
You'll need to turn the Diagnostic On. Use the catalog function on your calculator and scroll down to Diagnostic On and click Enter.

1 question: If we wanted to write down the equation of the line with fractions, how would we change it?
You can turn terminating decimals into fractions on the calculator by first entering the number, then press the MATH button, then press 1:Frac. Using the fractions, you can rewrite your regression equation so the coefficients are in fractional forrm.
Thank you so much :)))
What's that accent? It sounds familiar, but I can't quite put my finger on it...
Thank You sooooooooooooo much! I love learning!!!! xD haha
OMG!!! VERY helpful!!!

Thank you, very much. B
an Eo appears in my calc afeter I insert a value
can you tell me how toi arase that ?
thank you very much :)
my coefficient correlation doesn't come up
set your diagnostics to on
thanks your awesome :)!!!
for some reason i get err syntax when i press zoom 9
can anyone help me
Same
thx
I love you
^ ... state it directly, I mean
I mean saved me.
thanks, this vid actually helped. hahaha
