Finding Chi-square critical values with the TI-84

[@krystekmatysek2042]

OMG you are a lifesaver! thanks so much for showing me this.. idk why my professor couldnt show us this technique.. MUCH LOVE:)

[@ashley_young5429]

God bless you. Thank you so much

[@munbochoy342]

Been looking for this for ages, thank you!!

[@victoriaperez373]

I finally found a video that helped me solve these critical values. Thank you SO MUCH!!

[@whybslol]

very clear and straightforward. Thanks

[@ElijahNathanael-i8v]

I love you, thank you

[@commitmenttoexcellence]

extremely helpful and clear explanations

[@wnccmathandstats9399]

Thanks! I'm glad it was helpful!

IB students - Easier way: E1 = 1 - alpha-value; E2 = x^2cdf(0, X, df)

[@elrenee01]

Thanks for the tutorial! Working from the older TI-84 Plus and, silly, I know, I can't figure out how to clear the solver to start a new problem.

[@karlynnparker1455]

I cant either

[@karlynnparker1455]

press up and clear

[@chadly1337]

2nd quit

[@brockr6733]

For future reference other people in the comment section: after you finish the problem. Go back to 4:00 timestamp in the video ..... thats where you can edit the (0,x, ______) - _____ //////// just incase anyone else was stuck for a second like I was. Lol

I had a problem with 143 degrees of freedom with a Minitab printout of this. The book said to estimate using 150 using the table. I searched forever for this. Thank you!!

[@merbad4371]

Thank you!!!

[@brockr6733]

You are the best

[@jerrellyo7374]

thank you, your a life savior. :)

[@kendallconnelly8526]

after subtracting alpha/2 from the equation solver and pressing enter, i am not taken to the screen that shows the x value. when i tried an hour ago, it worked. i am following the video directly and am confused why it isn't working anymore.

[@quantummath]

good job! thanks for updating

[@kjartanvarbakken9825]

How is this calculated with TI-83 plus?

[@toxic-spammz1478]

You sound like Skyler White from Breaking Bad

[@joynoorichun676]

i don't know if there's something wrong with my ti-84 plus calculator, my x value always come out as 4500 no matter what....is there anything I can do?

[@mattstone4004]

Alpha->enter

[@joeklinck]

5:00 if you have a newer model

[@christiancamacho606]

The number subtracting the equation is 1-alpha right? I got the # I wanted when I did that not equation-alpha

[@shawnpavlik3756]

The number subtracted from the equation is alpha/2 and 1 - alpha/2.

[@dianagarcia5406]

I love you

[@israelojo7620]

Thank you! Quick question: I know how to perform L5 = L4 + 2 but if I create two new user-defined lists say A and B, I cannot perform A = B+2 (It does not work). Can you please help me with this?

[@shawnpavlik3756]

It probably is not understanding that A and B are referring specifically to lists. Can you use the L1, L2, L3 as provided, or do you have too many lists for that to work?

[@dianastoen2118]

I did not get the same value as the table.

[@25252525j]

I had a question? you said that your sample size is 18 so wouldn't your df be 17? I got a little confused..

[@shawnpavlik3756]

She said her sample size was 19, so dof is 18.
