Where did square root 3 come from? Is this a constant?
Lucid explanation
He looks like he's never frowned
I don't understand any thing because the accent is not good to translate maybe this is reason why there is not any comment. please find any way to fix this problem
Sir what is the limit value of combined uncertainty
Where did you get that 0.5 measurement uncertainty?
thank you sir for uploading this course
Thank you for explaining the "abstract" in plain and simple language for all to understand. Excellent work!
Great explanation. I think you need more pens in the pocket though, doesn't look enough.
Wonderful, Professor Leito. 👏👏👏
May somebody tell me why at 3:50 the professor says that the pooled standard deviation calculated for all 14 measurements corresponds to the situation as we made 11 measurements on a single day and on a single sample? Thank you very much.
Thanks for sharing the knowledge
I'm grateful prof ivo for the foundation you gave me in this subject and for simplifying measurement uncertainty
Thank you for the presentation. May I ask What about humudity?
చాలా బాగుంది
this guys accent sounds fake
Thank you very much sir. it's usefull for me
Superb
❤ great course great channel
Excellent 👌
Very clear explanation. Also a very soothing voice. Thanks!
Good lecture about the combined Standard uncertainty!
Nicely prepared lecture for the Standard Uncertainty!!
Thank you so much dear sir😊
Great! you can also see my lesson in topic. It may be a different approach. Update me about your opinions.
what is the uncertainty though? +- 1 microlitre?
One day I aspire to have more pens in my top pocket to beat your world record 🙂
Great video. Very well explained and engaging.
I hope this guy is doing well, such thorough but well paced lecturing!
i like your accent and the way you teach
I would not be able to stay awake in his class
I hope he doesn't take offence when he sees this comment! I agree as he's very relaxing, hope you meant the same
Superb lecture series! Thank you sir!
Have to respect someone who is so excited by his craft. It’s charming.
hello Sir, How you calculate standard uncertainty for single result. please reply
I think you should divide by the Sq root of n
You teach well, and your ASMR potential is absurd! I don't even like chemistry that much, but you made it so soothing to learn!
Amazing
Great and inspiring teacher. Kudos
How can i calculate the uncertainty of determination of total fatty matter in soap or whatever the kind of sample ?
you crazy man?
I feel threatened
Very useful for NABL accreditation lab... Excellent👍
Very useful to understand student distribution
That great
That's great
Awesome presenter! Utterly charming and instructive!
i love his voice

Thank you Ivo. Best explanation of measurement uncertainty I have seen so far.
