Crystal clear & nice explanation
Thanks for the video...

That's a very good explanation thank you sir

why in denominator you use f-1 ? why not f?

❤

Superb

where does 3 come from?

wow that was great and the explanation was good

Fantastic Teacher! I learn in 10 min. what would take days to learn from a textbook. Thank you!

nicely explained , thank yo sir

How to find frequency

Hi why can't the formula of σ2 = ∑ f (x − x̅)2 / n -(x̅)2 can't be used?

thank you a lot👍

this helps a lot sir what a crystal explanation🤔💯

👏❤very helpful

Made clear by u

nice and thanku very very very help full

Brilliantly explained, saved me from failing an exam. Literally Studying alone for exams and this guy, goat 🐐 ❤️

Why we divide the data with sigma(f-1), isn't we divide it with sigma(f), i am confused, anybody?

Thank you so much for this tutorial ...it's helpful😍😍😍🥳🥳🥳

thank you very much

Good explanation thanks

If I pull a card to try for the ace of spades (1/52 chance) and I win $500 each time I do, and $0 all the other times, how do I calculate the variance? each pull would be 1/52 (not 1/52 then 1/51 then 1/50...)

Is this method right or not if someone can tell me please

Why do you use (sum f)-1

thank you so much for making it a piece of cake😊
