Funny how a video like this teaches it better than school itself does lol

THANK YOU SO MUCH! My teacher gave us homework without explaining how to do this with the calculator! Such a big help!

This is the best video on TI-84 I have seen. Thank you for explaining what the abbreviated words actually mean. That helps me understand the steps better.

3:48 for turning the diagnostics on, if you have a TI 84 Plus CE, you can just click on mode which is next to the 2nd button and scroll down to Stat diagnostics and turn that on by going to on and pressing enter. You don’t have to go to Catalog.

Thank you Robert!!!

Its very helpful that you show us how to store the regression equation through the Y-vars - in other videos its typed in manually; )


Top advice M

PS Is there now a way to type in a value of 'x' and the calculator providing the correnponding 'Y'!??

I was just wondering what program you were using. I am so used to just using a document camera, but this looks much more user friendly. Could you let me know what it is and where you got it? Would really appreciate the info! Thank you!

I keep getting an error message after I enter calculate. When I select 2:GoTo, this is what I see. ExpReg L1, L2, Y1 Do you have ideas as to why this error message pops up? I followed all the steps exactly as your video.

what does the r variables mean at 5:04?

Some of the narrative is "Stupid" Such as "press the graph button here" I cant' read the computer screen and my calculator screen at the same time. Say rather " The graph button is at the top right of your device" Then go on. with the narrative.
