loved this, one thing I wanted to share something regarding the "you gotta do some math here" @ 5:45. I count my spaces to figure out the increments. For example, there are (5) spaces. and 10 tenths. so each tick mark would be 2 tenths. You explain it perfectly fine but I just wanted to throw this out there lol
I think its more a concept than a rule to use. Just keep this in mind when measuring. I think the answer would be it depends on what you're measuring. If it's something that needs to be extremely precise then the range would need to be very small, not everything needs to be perfect though. There is a degree of uncertainty that is acceptable depending on what the application is.
the .02 comes from the estimated hundredths place on the measurement of the graduated cylinder - replay that part and listen carefully. I was confused at first, as well.
isn't it because basically it goes up in intervals (whole numbers) of 1mL, but there are 5 sub markings in between. so 1 divided by 5 and then move it one place to the left which turns into 0.02 (this is for every reading, not just this video).
2:46 it’s 6.70 at leats if you read off the values from the bottom of the meniscus.
Its just above 6.6 if you read the bottom of the miniscus. with a accruacy of +_ 0.1
@Saul Otis no one cares you stalker ass bot

Thank you very much this was very helpful Sr. This goes straight to my chemistry playlist.
The reading on the measuring cylinder is closer to 6.60 than 7.21
Hi, I was wondering if anyone knows what is the best for determining accuracy in measuring a solution? Mean or standard deviation?
What would be the range in order for us to tell that the measurements are precise

So helpful! Thanks a lot (new chemistry teacher)
It was quite useful, Thank you!
what is a different between uncertainty and precision
Uncertainty is always half of the precision
ex; 1.5cm (Precision) -> .5cm (Uncertainty)
For the last measurement, how did you come up with the 0.02 as the uncertain? where did that number come from?

thankyou very much sir workman
This vid is cool, I liv you guys
You ignored the importance of the uncertain digit !
Legend man! Understanding this stuff better now!
thank you
Thank you so much ❤❤
love this vryy niceee
Awesome thx
excellent description
Who’s in Phillip’s physics class?
*proceeds to precisely measure liquid*
I love science 😊😊😊😊😊😊😊😊😊😊😊❤️❤️❤️❤️❤️❤️❤️❤️❤️
