Chi-Square Test for Independence for TI-83 & TI-84

[@natalieelkins7324]

Thank you. I am borrowing my son's TI 84 and haven't taken math in many years and never had a TI-84 to use. Thanks for your easy to follow, Step-by step tutorial. I'm excited to use this new found knowledge on my upcoming exam!!

As a college student struggling through studying for my stats final, THANK YOU❤️❤️❤️❤️❤️❤️❤️❤️

[@lindapaz8936]

This was an awesome video. Straight to the point and easy to follow. Thank you.

[@shelbyebanks6983]

Love your videos, because they are to the point and easy to watch. Unlike some other videos which gives you a bunch of unnecessary lecturing bullshit which has nothing to do with solving the problem.

Thank you so much for putting so much effort into this. My Calc professor is having us perform all calculations by hand (to understand why these are input) but it’s a 7 week course and frankly it’s impossible. This has made my life so much easier and as it should be, considering this is how real life application is performed

[@noahe2991]

my course did not sum up this technology test as neatly as you did

[@JustOllieYT]

Thank you so much for this video, thank to this I was able to finish my maths IA

[@mason.11]

Absolutely perfect tutorial for me! Thank you!

[@kingfavy6740]

Thank you very much, you have no idea how much help your videos are

[@juliam.9423]

I followed all of the steps to the t and every time I hit "Calculate" my calculator gives me the "Error:Domain" screen. Maybe I'm missing something?

[@Bookjakani]

Same here!

[@Xhoro20]

I realize it's to late for my comment to help you, but in case it helps anyone else you need to make sure the values are all integers. No decimals or fractions in the matrix, or itll get freaked out

[@joeblackjackal6288]

Hope you are not using t distribution, this is chi square, and if it freaks out is because ur L1 and L2 or data frequency are empty, hence the error!!!!

[@hotvindilu1]

@@Xhoro20 Thank you lol I was getting the same thing. It sucks because if they have to be integers, that would require rounding, which seems like it'd throw the X^2 value off. This is especially damaging if the exam calls for the individual to do a short answer problem. Multiple choice may be doable as the values could line up approximately, but short answer means you're screwed because the X^2 would be further off target.

You have your O and E in the wrong columns.

very useful since the hawkes online program doesn't do demos but screenshots of how to do it

[@angieconger9540]

Thank you! This was so easy to understand. It was enormously helpful.

[@daysiperez7084]

Great video. Does anyone know what word processing software she is using to flawlessly get all of the symbols? Thanks!

[@OpenIntroOrg]

We tend to use LaTeX* for much of our work, but I think in this case it might have been a Word or Google doc using the "equation" mode. *LaTeX has historically been used for a large number of textbooks. It is a free, open-source software. In our experience, it's a bit more pleasant to use on a Mac (search "MacTeX") with TeXShop as the interface than the experience on a Windows computer.

[@Stop_Sign21]

Thank you I forgot

[@pricetopay5152]

bless your heart

[@samanthamoses4321]

ti83 doesn’t even have a matrix button

[@OpenIntroOrg]

Hit the 2nd button, and then 3 buttons below the 2nd button. MATRX is in yellow above that key -- when you hit "2nd", it gives you access to the yellow options on each key for the next key press.
