Honestly saying that you are a absolutely amazing professor. The way you explain its really really helpful for me as well as others.I understand everything Whatever you explain. Thank you sooo much for your excellent videos,I pray for you from my heart❤️
I SWEAR IM GONNA PASS MY MATH EXAM AND ITS GONNA BE ALL THANKS TO YOU AND YOUR VIDEOS NOT MY USELESS DUMBASS MATH TEACHER THAT JUST GRADUATED FROM HIS COLLEGE, THANK YOU BRO
This channel has helped me greatly with studying for my chemistry final so thank you so much, keep up the good work. Subscribed because your awesome at explaining.
Professor Organic Chemistry Tutor, thank you for a short and sweet video/lecture on How to Calculate the Percent Error of a Lab Experiment in AP/General Chemistry. This is an error free video/lecture on RUclips TV with the Organic Chemistry Tutor.
u literally save my life tysm, ive watched multipleof ur vids for just one assignment cuz its on different topics. ill come back when my assignment is graded:)
OMG BECAUSE OF YOU IM PASSING MY MATH TEST THANK YOU SOOOOO MUCH😭😭😭😭😭❤️ MY DUMBASS CANT UNDERSTAND WHAT MY MATH TEACHER SAYS😭😭😭😭😭but I still dont really understand some of the words TYSM I still learned a lot!!!!
Yes, you can not have a percent error that is negative, (-)x% doesn't make sense (it does not mean anything). Abs is there so you can have a positive value in terms of the %error.
What if there was multiple error values, lets say Data 1 error is 0.154 Data 2 error is 0.054 Data 3 error is 0.254 Data 4 error is 0.046 Then do I have to add them and divide by 4? Same to when getting the average? ( Data 1 + Data 2 + Data 3 + Data 4) /4 = Average
hello can i ask what if i get a (-) negative answer by calculating the percent error, what does that mean? am i doing something during my calculations or is it normal to have a negative answer?? thanks!
Usually you'll be given a certain amount of significant figures required in the answer. Look up the pacific-atlantic method for significant figures if you're having trouble learning those. But in this case if you were told four sig figs, it'd be 3.762. If you were told 3, it'd be 3.76. Since the decimal is present (pacific) we start counting from the first non-zero digit on the left. If the decimal were absent (atlantic) we start counting from the right. Get it, cause the pacific is on the left of the US while the atlantic is on the right? present, absent = pacific, atlantic

its been 7 months
This is way simpler than what my teacher wants us to do. Thanks
this channel is a literal lifesaver
You just saved my grade, thank u so much
Oh my gosh 👍👍👍😉 u really helped this is nothing compared to our teacher thank u so much
RUclips be teaching me better than my teacher
Me to also bro
Same 😂😂
Sameeee
Innit
Frrrr😅
Who else is here for science???
Meeee
meeeee
Why else would anyone be here? Leisure? If so, you have idiosyncratic tendencies

Sir, you english voice is very clear I always see all problem on RUclips on your channel.
Thank you, I got a state test coming up and needed to see this
its my chem teacher’s first year teaching chem so he is still learning everything. i really needed this for my quiz.
My teacher does not help half as much as this did thank you very much 👍👍👍
thank you i completely understand it and i realized what i was doing wrong ! very helpful !
Thank u so much, you helped mw with my math quiz (:
Thank you.I needed this for my analytical chemistry class🤣.
You're cute.🤣
I'm failing chemistry I needed this
truly this is a clever way to explain this, thank you😀
btw im from philippinnes Grade 12 currently your videos help me a lot to understand my math lessons
if this guy was my chemistry teacher, chemistry would be my favorite subject
thank you so much bro for this you save my life😌
OMG BECAUSE OF YOU IM PASSING MY MATH TEST THANK YOU SOOOOO MUCH😭😭😭😭😭❤️ MY DUMBASS CANT UNDERSTAND WHAT MY MATH TEACHER SAYS😭😭😭😭😭but I still dont really understand some of the words TYSM I still learned a lot!!!!
Ya but for me it’s not that simple, my teacher gives us word problems and it doesn’t tell you which one is actual or measured 😭
Jelly_belly101 _ same here, I get the concept, but the wording is weird.
What a shit teacher
@@mt6699 you can base on the least significant figure
read ur word doc carefully it must be there. Don't blame ur prof.
weird
Thank you this is going to get me through midterms
THANKYOU FOR MAKING THINGS EASIER ❤❤
My unit test is tommorow. This is one of many things i have to study
He should get a award.
Thanks man it's simple and easy to understand
..
thank you so much! the video helped me a lot.
You saved my grades in Physics 💓
bro which calculator r u using iam not getting the same answer can u be more specific sorry but please
Thank you so much you saved my life
I had a math test worth 50% of my grade, thank you for the help
where do you find the actual value??
Thanks for this helpful video ❤
Name a better chem channel …
I’ll wait
If you have no actual value, can you set the mean is an actual value?
Thanks for the lesson 💐
3,000th like
This really helped with my math homework. Thank you!!
If 7.7 and 7.86 are the control... wouldn't the sig fig be 2? And if so, wouldn't the correct percentage be 2.0%? I'm confused...
Thank you so much bro
Where can i get the experimental value? Is it the average value? Or you have to find every percent error for the experimental value?
I have a test in 2 days thankyou so so much
Lowkey I fell in love with his voice 😭
This was so incredibly helpful!!!!! Thank you so much!!!!
You are a godsend
Due to pandemic I could not understand anything
Thank you for explaining
Dude thanks you always help me 😅
Should the formula of “Error = measured - actual” be in in the absolute value? So instead the formula should look like “Error = |measured - actual|”
yes it is in absolute value :)
Angel White Thank you 🙏🏽
Does the volume of the cylinder equate to messured area and total area to actual area?
Do you always change it to the absolute value?
1 year and still no answer...
Yes, you can not have a percent error that is negative, (-)x% doesn't make sense (it does not mean anything). Abs is there so you can have a positive value in terms of the %error.
i legit love u bro
What about writing the answer with the correct significant digits? How do you determine that?
Just wanted to ask, how much accurate will the measurement be if the % error is less than 3%?
What if there was multiple error values, lets say
Data 1 error is 0.154
Data 2 error is 0.054
Data 3 error is 0.254
Data 4 error is 0.046
Then do I have to add them and divide by 4? Same to when getting the average? ( Data 1 + Data 2 + Data 3 + Data 4) /4 = Average
Up
My exam is today you help me Thank you
everyone has a hero, zero people shouldn't have a hero, organic chemistry tutor is my hero, he is really nice........
no logan paul parodies
thank you so much for explaining it so well i love you
what does the % error of each experiment mean ?
What is the error in the computation of trends and responses?
Do you have a video tuts for solving
% deviation?
But how do you find actual value I don’t get this
bruh you litelary just might save my ass from failing fysics. Apritiate it bro
what if there is no actual value given?
Li Kying no one is answering
There has to be one
Thank you for everything you really helping alot of students
Hi! i just wanna ask if there such a thing or a formula for multiple trials but with only one outcome??? thanks in advance
Thanks for saving my grade in the one unit i got lost with
How would you do this: a dogs weight decease 5% last month if he weighed 30lbs on the first of the month , what did he weigh at the end of the month??
Where in the steps do you choose how many significant figures the answer will be (4 significant figures) --> 2.036%?
Did the measured and actual need to have the same number of sig figs to subtract?
Where can i get the actual from the measured percentage or error?
Sir how about the relative and absolute error? If there any examples of that?
Well explained
In the first example how did he get 3.7% (the final answer)?
What's the complete process?
Been stuck for almost three days
How many sig figs do you have to round to
hello can i ask what if i get a (-) negative answer by calculating the percent error, what does that mean? am i doing something during my calculations or is it normal to have a negative answer?? thanks!
You have the absolute error divided by the actual value times 100%, so it is impossible to get a negative answer for the percentage error
@@stelaririna yes, already answered it! i forgot to put the absolute value while solving, my bad😅 thanks!!
@@yoshgrande5037 I just saw that your comment was 2 months ago, oops 🥲🤣
Did u round up from the measure to get the actual
How do you get the accepted value of the element?
measured - actual or actual - measured?
What does 'absolute value' mean?
Thanks saved me!
since u get it why did he remove the negative from -0.1?
Thank you sir for helping
Thank you so much, sir
Does anyone know how to do this with significant figures?
Sure
Thank you this is so helpfull
THANK YOU!!!!!!!!!!!!!!!
how do you know when to round, what I mean is for example the answer is 3.76237821222123 when do you start rounding
Usually you'll be given a certain amount of significant figures required in the answer. Look up the pacific-atlantic method for significant figures if you're having trouble learning those.

thanks
I always do it too 2 decimal place unless it state otherwise.
Where u take the absolute value from
Ep=(M-A)x100%/A
Thanks this helped a lot
