Elementary Statistics: Finding the Sum of the Squared Residuals on TI-83-84 

Rocheal, sorry I didn't get back with you sooner. Don't get on as much in the summer time. Probably too late for you but one of two things: 1) make sure that you have the same count of numbers in L1 as in L2. For example if you have 5 numbers in L1, you have to have 5 numbers in L2 or you will get an error. 2) make sure L3 is highlighted before you type in the formula you see in the video. 3) make sure you have done the LINREG function before doing the lists. Hope this helps! David

Awesome :) I looked for help on this type of problem for quite a while, and this was the only good example I could find. Thanks a lot!

I usually don't post comments, however, this video deserves some appreciation. Thank you for the video. It was very simple to understand & clear with step by step instructions. thank you

Thank you man. It was the only thing I don't know how to do for my upcoming test. Now I do! :)

i would like to just make this clear DAVID HAYS FOR PRESIDENT I am forever in debt to you

You are a gentleman and a scholar!

This is an EXTREMELY helpful video. I could not find the answer to this question on any website, or even in my textbook. Thank you!

I... love you ;_; Thank you so much! My teacher was trying to get us to do all this by hand and I was running out of time on my quizzes. You are truly a life savior!

was watching this video and thought, " this voice sounds familiar". Sure enough, my old college algebra teacher;) Thanks for the help!

Excellent. I will definitely point my students to this video. Thank you!

wow! you are like god right now. thank you so much!!! I needed this to find the standard error of the estimate for a single regression model. and I got it! so simple, ill have to show it to my studygroup! thanks!!!

Thanks a bunch, this helped a lot with my Business Statistics 2 class.

Thank you so much for this video, it really helped me understand EVERYTHING.

You are a lifesaver. Thank you

I wish I could thumbs up this 1 million times!!! omg thank you!!!

Outstanding. Had no idea you could put functions in the list name itself to autopopulate.

thank you so much for sharing this! I was breaking my brain trying to do this.

Very VERY helpful! Thanks for uploading!!

You are amazing, I was not doing linreg first. Thank you, heading in to write exam now....

Or you could just do sum(RESID²). RESID is located in 2nd/STAT/NAMES, and sum is located in 2nd/STAT/MATH.

Much clear now!

Extremely helpful !! Thank you!!!

So when I am entering the L3 line it keeps coming up with ERR:Undefined, can you help with this?

Thanks for the help!

You are welcome! David

You are welcome!

Awesome, awesome. so thankful.

Great video.

Awesome! Thanks you so much

Hi, David. This is going to be very helpful, I think, in helping me to find the SS(x), the SS(y), and the SS(xy). When I type in the formula for L3, upon hitting ENTER, I get an error. Can you please help me with this?

Sounds like you didn't square them before doing the sum. If you add just the residuals, they will add up to zero but if you square them first, then you will get the answer. Have a good weekend!

thank you so much!!!!

Thank you!!!!!

sooooooo helpful!(:

DUD THANK YOU SO MUCH. saved me from ripping my hair out :D

There is a much easier way to do this on your calculator I hope you know that? "sum(RESID^2)" don't have to put in L3 or L4 still have to run the LinReg but that's it.

I am not worthy!!!!
