I was nervous when I saw equations like this come up in my physics 1 lab so I stopped and came to UA-cam. This video made it look very easy! Thank you for this great explanation!
Thank you for the informative video, If the equipment errors is larger than the standard deviation? how do we write the uncertainty value for the final results?
Hello is this as per NABL guidelines ? and what is the difference between Standard Deviation, Uncertainty, Acceptable error and Tolerance ? In this video you explained uncertainty for 3.40 is ±0.4 is this also the acceptable error limit. I also want a clarification on all this parameters. Thanking you, Awaiting for your reply.
Hi Prakhar, Thank you for asking. The information in this video meets no industry standards criteria. It is video I used for educational purposes. Please consult the appropriate industry standards for their standards.
You are correct. When I first posted the video I used a UA-cam feature to add a note about the incorrect range and I corrected it then. However since then UA-cam has discontinued that feature feature. I found an alternative way to add a note to add a note to that section of the video. Thanks for your comments.

@@CALettsomePhDPE Uncertainty and std are not the same thing: Uncertainty takes into account the std deviation and not the other way around. which means they are directly related, but they are not the same. I work with wind conditions and when calculation the uncertainty of measurements you need to take into account, the range of the measurement equipment, the std of the samples recorded, etc. Hope that helps, surprised you considered those are the same.
Hi AC7plays, Thank you for asking. Unfortunately I am not doing any tutoring. There may be other videos on UA-cam that maybe able to help you do so. Good Luck!

really nice description - i think i FINALLY feel comfortable with this
One of the best illustrations i have ever seen for explaining uncertainty.
Keep up .
actually lots of wrong things happening there!
Thank you so much I did uncertainty calculations for my ICP-MS AND ICP-OES your video helped me very much.
Thank you.

Thank you sir best wishes from Sri Lanka 🇱🇰

Thank you so much. I was basically lost in this equation but you made everything very clear.
Glad it helped!

In end x bar value not put in formula please tell me
Yes. nice explanation but it think it should be in a range of 3.40 - 3.48 (as it is +- 0.04 and 3.44 is the average value)

Is there a difference between standard uncertainty and uncertainty or are they the same thing
Thanks! I was really lost in lab and this clarified a lot!
Very helpful, thank you so much. I have struggled to distinguish those for quite some time.
Glad it helped!

Thank you Sir. Your video is very helpful .
3,40 - 3,48

Finally!!!!! Thank you so much for posting this video!!!!!!
No problem!! You're welcome!

Sir I had a question.........Why did u use the sample variance formula instead of the standard deviation for population formula?
Same here, I'd like to know that
Very nice , this is standard deviation or uncertainty calculation or both are same?
Because all times i had a problem with uncertainty calculation and now if it is what video contents it will easy for me ....thanks
They are the same.

Dear, shouldn't we write the final answer as 3.4 instead of 3.44 since the uncertainty has one sig fig. ?
No, the result and the uncertainty should have equal number of decimal places: 3.44 +/- 0.04. Another examples: 5.3+/-0.2 ; 5.300 +/- 0.225
Last py kesy howa hy???
Sir please help me in calculating unceratinty of T^2 using standard deviation (t=time period)
Hi AC7plays,
Thank you for asking. Unfortunately I am not doing any tutoring. There may be other videos on UA-cam that maybe able to help you do so.
Good Luck!
how 0.0016 to two significant figures is 2 * 10 pwr - 3 ... is beyond me
I think this will help. ua-cam.com/video/ebzviH1E0yU/v-deo.html
In few books, in the denominator , n is there instead of n-1 .
Aditi Mishra It will be the case when your n>20 else it would be n-1 only
3.40 ... 3.48
tq..very good teaching
