Statistics - How to use Chebyshev's Theorem

Hi,
Could you please explain to me why you got 12.82 as Standard diviation?
I got 38.92 as my Standard sample diviation. I already watched your previous videos, but I still dont get the same result than yours.
Thanks

i really love this guy

I've been struggling in my graduate level Stats for Experimenters class and your instruction is SO helpful. Thank you!

you lost me with all the shortcuts I can't turn in shortcuts

i can not thank you enough for this.
you saved my grade sir

so well explained wow

where did you go on the calculator that looks for all the info (mean, etc)

Where does the 3 come from in Chebyshev's theorem? How does 1- 1/4 turn into 3/4?

Thank you so much you made it 100 times easier

Sir which type of calculator you used ? please tell me model name & price & from where i can buy this type of calculator

Appreciate you fam

Thank you, Sir! You are great!

Thank God for you! I did not understand this when my professor explained it, but now I will ace my homework thanks to you!

What to do when k is less than 1?

Bless you

very well explained .thanks !

Nice lecture 👌. Helps me to solve my assignment question. Love from India❤️

It sure did help!
Thanks a million <3

So basically, using Chebyshev, means you're always "at least 75%?" I don't understand the point of the little formula if it always means 75%. What am I missing?

Really appreciate your work and help

thaaank you

very good and enough explanations thanks a lot

how did you plug in the 30 data points for the SD and mean on the calculator ?

Bro just came in clutch helping me finish the last question on my test, much thanks

Thanks so much

Wish u were my math teacher... thought statistics was hard buh you make it so simple to understand 🔥🔥why do most math teachers make simple things so hard aaaaaaaaa

Thankyou so much, this theorem is on my homework but the teacher and textbook haven't taught us this yet lol..so thankfully found your video!

But what if the distance between the two intervals are not equal in distance from the mean?

I have one question what if I want to know how much data lie between two different standard deviation. here both lower limit and upper limit ($22000 and $50000 respectively) are equally apart from mean . what if I want to calculate data between lets say $25000 to $60000?? do i need to calculate k value for both limit and substract the percentage between them??

U r best 👍

Thank you very much! I was stuck on a problem like this for over an hour.

The name of your yt channel is like a porn video caption

1-¼... how did we get ¾ from that?

Thank u so much

Oh ma God, maths difficult😢

thank you from Oman 🇴🇲

thank you, and the neat handwriting makes it so much easier to follow! it was hard following my uni professor😭😭

can someone explain why 1-1/4 turned into 3/4?
