You just made my life so much easier! Thank you!

Anybody know why the standard deviations & variances my Casio calculates are completely different from those calculated on my professor's TI-84? I keep getting questions wrong because the decimals on my calculator are always incorrect, ex. the correct answer is 7.334 but I get 7.776 when I calculate it :( I've reset it multiple times & I'm calculating it correctly, so why are my answers inaccurate?

Do you happen to know how to switch between getting scientific notation for an answer vs getting the answer as a regular decimal? I have to switch between using this calculator for Chemistry and Calculus and it's getting confusing when I keep getting answers that end in E to something.

This video was so helpful, thank you!! I feel kinda silly for not figuring this out myself haha, it's much more simple than I thought

Would you be able to a demonstration on how to use the Z and the T-test?

Man I can't believe I've been doing this by hand

Thank you! My class is using a different calculator than this, so I couldn't figure it out. So simple!

Hello, I have a casio fx 9750gii calculator. I took a pipe fitter program from my colleagues, but when I put in the measurements, it gives me a mistake. Any idea how I can fix the problem?

On my 9850GC plus I get the answers presented like you, but for sigma x it's called "[x {sigma} n]" and the sx is called "[x {sigma} n -1]" All answers are else identical. Does this matter at all?

how do you keep that list and do a sub list on list 1?

I did everything in step 1 but when I press F1 it tells me I have an error. I did it 2x..is my calculator defective?

Same here, did you figure out the issue?

Go to set, set your 1var freq to 1

thanks

Please make a video to show if this calculator can show significant figures

Thank you!!!

I did everything and mines comes up with all zeros and a 1 for n? I'm I missing something?

hey you didn't tell us how to clear the data and start fresh; (found it.. one must press DEL on each value to start fresh) thanks for this video by the way

i love you

thank you so much :)

ty very nice

Yoooooo no frickin way dood

How do you find absolute value using this calculator???

@MySecretMathTutor

There are a couple of ways to do this.... 1) [2nd] [4] This will access the catalog of functions. You can then scroll down and select "Abs" for absolute value. Abs will show up on the screen. But the number in parenthesis after the Abs. So Abs (-3) should return 3. 2) [OPTN] [F3] This will access the menu for working with complex numbers. The 2nd option here [F2] will allow you to use Abs. Hope that helps out. :^D

How do you use/add infinity when using normcd?

This example is for working with a given data set of say "n" values. If you have function that represents a random variable then I suggest finding the variance first using Var(X) = E(X^2) - (E(X))^2 and then taking the square root. Here the expected value E( ) is calculated via an integral. E(X) = int_{-\infty}^{\infty} x f(x) dx Hope that helps out. :^D

@@MySecretMathTutor for example when im using normcd or normpd and I have to put the lowest and hightest # , I can use -10 if going backwards but for the higher I need to put infinity which looks like 1e+99 on the casio but I cant figure out what buttons I push on the casio to give me the 1e+99. Thank you for your help!
