I am Muslim and you can say things in a better way. Only Allah Swt accepts who will go to heaven not us.. In Islam, we do not even know if we are going to heaven 100% so we should be people to strive in the way of the truth.
Bilal Younas - Idiotic, mindless, unrealistic, and self-oriented people like you are the reason Islam has such a bad name today. You should take that offensive and controversial comment down. By the way, I'm a Muslim and I literally was embarrassed and ashamed to to see someone say something that awful. All the hate for our religion is better justified than the reasoning for our decisions on what to say and do when it comes to people like you. In the Qur'an it states that all people will be judged based on the righteousness of their decisions during life, not purely their religion.
I think it is more about how the answer would be correct if you use significant number to make the answer less precise , becouse if you start with less precise numbers they are most probalbly round up at first place from their precise form so when you calculate these rounded numbers you must make the answer less precise to make sure its more correct than the unprecised answer.
Hi, Tyler DeWitt , I am a chemistry lecturer from India. I really like all your videos on Significant figures. Great job ! It has clarified some of the FAQs of my students and mine too !! Thanks again, keep up the good work !
Your analogy is brilliant. Really made this concept click for me--I only wish teachers could explain it as easily and clearly as you did...then we could all avoid the headache of students complaining that this concept doesn't make sense. Teachers set themselves up for failure when they present sig figs as this obscure and bizarre concept that no one understands. Thanks so much for this video!
Hats off Tyler. My 30 years of failure in understanding this concept was done straight after seeing these 10 simple, excellent and extraordinary video clips. You are a Star. You are a light.
Oh my god, you are the best. today when I went to my physics class and didn't get the explanation, I wasn't procrastinating as I knew about your channel before and also that u must have made a video on significant digit already. now I can confidently walk in class as your lesson made everything crystal clear. one more thing I also really like the way your video are format, they seems so professional, Keep up the good work.
wow. thank. you. I FINALLY UNDERSTAND WHY IT MATTERS!!! I asked my college professor to explain this and he wasn't able to explain it in an hour lecture... as great as you did in 7 minutes.
jesus!! thanks god for the last video. i ve seen all the nine videos before in a raw getting pissed off for your different approach. and than, here you are again in the last one with the same effective method ; making examples, making me care, showing the point. every teachers in the world should learn how to teach like this, especially here in italy. I THINK WOULD BE EVEN BETTER IF YOU TAUGTH TEACHERS HOW TO TEACH!
No one taught me this at college. They said just f-ing do it this way. I used to plug my numbers in a formula after each chemistry experiment to calculate the standard deviation with out knowing that is standard deviation 😅
I was creating my first videos on UA-cam and I met you for the first as a math student and student tutor.... And honestly not explanation is off the chain.... Awesome job bro
Thank you so much Taylor, I look around alot of video which doesn't solve my question except yours! You are gifted with chemistry and explaining , you are a hero to save my chemistry.
my chemistry teacher told us that on some problems we shouldn't use sig figs or else we will get a really inaccurate answer and when i asked her how will we know she said you just will. and sure enough on a test there was one such problem and of course i didnt know and used sig figs getting the answer wrong and i still dont quite understand. so you use imprecise measurements and get an imprecise answer that just looks precise so you need to make the imprecise answer less precise just to make it so that it doesnt look precise?
we don't mean to show it imprecise.... but it doesn't make sense to write the whole answer (with all decimals) because it is uncertain, meaning thereby inaccurate...So we show that the answer is 1.9 that is it lies between 1.86 to 1.95 ...... we are uncertain at 1st decimal place ... so it doesn't make sense to show the further decimals... i hope you get it now
THANK YOU SO MUCH~!!! I HAVE BEEN SO CONFUSED ALL MY LIFE AND U CLEARED IT ALL FOR ALL OF US~!! SO VERY GRATEFUL~~!! I hope your days are easy and happy, Sir ~~!!
When you said the MASS of the rock was 82 grams, I think you meant VOLUME..... Just kidding. I was pretending to be one of those people that feel the need to correct you over absurdities. I'm so thankful for your videos, you're going to be the reason I make it through this semester!
This video is really very helpful for the students to understand the importance of significant figures. Thank you very much for posting this..Bless your heart..
That was an EXCELLENT example! I understood the whole of the concept becoz of just that one real life example.....do try to include examples like these....makes us understand better! Thanks a lot! may gid bless you....
I have a question, hehe, I've been thinking, let's say you have a big piece of land, and by some reason you want to put 3 division pieces of 3 meters, you have a ruler that can only meassure one decimal of meter, so you meassure 3.0m. So now you multiply 3.0*3 and you get 9.0m right, same precision you begin with, but now that you see that it will only take 9.0m you say, well, I rather make 4 division of 3 meters, so again you multiply 3.0m *4 and now you end up with 12, but, you can only have 2 significant figures, so your result is actually 12.m not 12.0m, but if you instead of multiplying you make the sum, you end up with 12.0m, so what to do? I mean from your instruments 12.0 is doable and with the same precision as your instruments. Or lets say you have a land of 12.0m and you want to divided in 5 pieces, , now you have a by significant figures, 4.00m but that is way more precise than your instrument, but you have 3 significant figures just as the one you begin with. Or in your very example you end up with 2.0 grams per cc, but that .0 is more precise than your instruments, that .0 you cannot know it, because your instruments cannot meassure a decimal of a gram.
Omg Tyler. Thank you so much. I thought I was going to fail Chemistry after the first chapter! This helps so much because I read the chapter and was like: So the F What!
Hi Tyler, you are an awesome teacher and thank you for making all these videos! I only have one question about one of the words you used in this video. Why did you use the word precise instead of accurate? Based on the definitions of the two words, isn't it better to use the word "accurate" since the rocket laser scale can measure something closer to the actual value?
waow..this is soooo cool,am not an experience student in the science class after more than 6years studying management course,but hope this video will help me in the science faculty in my A /AS level programme ...thanks alot . Tyler DeWitt.
awesome tyler is the man! But question??? is accuracy a better term than precise for the locations downtown, since precision means close relative to other measures, whereas accuracy refers to close to true measure (like the actual location)? (which I learned from tylers other videos haha) THANK YOU FOR TEACHING ME
Hey man, awesome video. So essentially the heart of the problem lies in the fact that in chem/physics we often measure things and it is basically impossible to get a measurement that is 100% correct right?
Ooooooooh my gosh I've been so confused on why significant figures are important for so long and they've been so frustrating and this makes perfect sense
When we estimate mesurement uncertainty in chemical measurement the general rule is that we put the final answer in only either one or two significant figures. Are we being more conservative here because some of our measurements that we used may have only one or two significant figures while others may have more significant figures?
2017 BRO THIS GUYS IS awesome!!!! and HELPFUL!!! thx bro I am in high school and its the biggining of the school year u teach even better than my teacher's ur awesome:) thx for the help
BLESS YOU THERE IS A SPECIAL PLACE IN HEAVEN FOR PEOPLE LIKE YOU WHO MAKE SENSE WHEN THEY EXPLAIN THINGS
I am Muslim and you can say things in a better way. Only Allah Swt accepts who will go to heaven not us.. In Islam, we do not even know if we are going to heaven 100% so we should be people to strive in the way of the truth.
I can't believe people still believe this xD
Bilal Younas Such a primitive mindset.....
Ashamed of you
Agh wait no I made this comment to appreciate Tyler and his teaching not to spark a debate on religion
Bilal Younas - Idiotic, mindless, unrealistic, and self-oriented people like you are the reason Islam has such a bad name today. You should take that offensive and controversial comment down. By the way, I'm a Muslim and I literally was embarrassed and ashamed to to see someone say something that awful. All the hate for our religion is better justified than the reasoning for our decisions on what to say and do when it comes to people like you.
In the Qur'an it states that all people will be judged based on the righteousness of their decisions during life, not purely their religion.
This man single handedly carried me through high school when my teachers would get mad at me trying to explain everything. Thank you so much.
Stop moving my hands? Sorry, not gonna happen. But I'm really happy that you found this video useful.
You don't need to! Thanks Tyler DeWitt
You're amazing and I love your videos so much!
SIR THANK YOU FOR MAKING THESE INCREDIBLY USEFUL VIDEOS :) LOVE YOU SO MUCH!
gesticulation is a virtue
I think it is more about how the answer would be correct if you use significant number to make the answer less precise , becouse if you start with less precise numbers they are most probalbly round up at first place from their precise form so when you calculate these rounded numbers you must make the answer less precise to make sure its more correct than the unprecised answer.
11 years later you are still a legend. All your significant figures videos are great!
Hi, Tyler DeWitt , I am a chemistry lecturer from India. I really like all your videos on Significant figures. Great job ! It has clarified some of the FAQs of my students and mine too !! Thanks again, keep up the good work !
Thank you for taking time out of your life to put up all these amazing videos for helpless students. You are my hero!!
Amanda Mason ....True, very true
I thought it said hopeless 😩
@@Franciscoo___ me to
Finally found a good explanation of the why behind significant figures. Awesome explanation, thank you.
I'm so happy you liked it! This is one of the my favorite videos that I've ever made!
"I measured both of these with plastic science equipment from the Barbie playset"
Gets me every time.
Thank you so much my teacher was trying so hard to explain this to me but I just wasn't getting it. I watch this and it immediately makes sense!!
Your analogy is brilliant. Really made this concept click for me--I only wish teachers could explain it as easily and clearly as you did...then we could all avoid the headache of students complaining that this concept doesn't make sense.

I’m very sensitive, but your passion for educating made me tear up at the end of the lesson. Thank you for your help!
Extremely helpful explanation that even an idiot like me could grasp. Just starting a science degree and this helped a lot, thank you.
From Egypt, really I didn't find anyone explaining so wonderfully like that I hope you continue to Download videos
wow. thank. you. I FINALLY UNDERSTAND WHY IT MATTERS!!! I asked my college professor to explain this and he wasn't able to explain it in an hour lecture... as great as you did in 7 minutes.

Many chemistry teachers came in my life but it's only you who has satisfied me 🙏
That is really funny. I will never forget this because it is very logical.
Thank you! This is one of my favorite videos that I ever made!
Tyler DeWitt This video taught me something I had never even thought about. Thank you for contributing your knowledge to UA-cam as free education.
No one taught me this at college. They said just f-ing do it this way.
I used to plug my numbers in a formula after each chemistry experiment to calculate the standard deviation with out knowing that is standard deviation 😅
Great analogy man, thanks. Helped a lot!
By far, this is the best tutorial i have seen . Thank you and keep up the good work. you are a tremendous help.
I was creating my first videos on UA-cam and I met you for the first as a math student and student tutor.... And honestly not explanation is off the chain.... Awesome job bro
Explained it better than any teacher I'd ever had. Thank you so much.
Loved the analogy
watching from India. 🙏 nice stuff sir... 👍
This is an A+ example of a well-explained video. Keep up the great work!
Thanks a lot. Sharing one's knowledge never fade up, you have uploaded this 8yrs back and now am getting used of it. Love the way of ur teaching ❤️
Thank you so much Taylor, I look around alot of video which doesn't solve my question except yours! You are gifted with chemistry and explaining , you are a hero to save my chemistry.
Thanks, u r such a good teacher, u r better than my highly graduated chemistry and maths teachers, love from india
Thank you so much for this series, tyler. It helped me a lot. You are amazing teacher❤❤
my chemistry teacher told us that on some problems we shouldn't use sig figs or else we will get a really inaccurate answer and when i asked her how will we know she said you just will. and sure enough on a test there was one such problem and of course i didnt know and used sig figs getting the answer wrong
and i still dont quite understand. so you use imprecise measurements and get an imprecise answer that just looks precise so you need to make the imprecise answer less precise just to make it so that it doesnt look precise?
we don't mean to show it imprecise....
but it doesn't make sense to write the whole answer (with all decimals) because it is uncertain, meaning thereby inaccurate...So we show that the answer is 1.9 that is it lies between 1.86 to 1.95 ......
we are uncertain at 1st decimal place ...
so it doesn't make sense to show the further decimals...
i hope you get it now
You should do a video of significant figures in combine operations.
Your explanation, it just makes so much sense. Thank you
Finally a video where someone explained the IDEA of sig figs! -- A Chem teacher looking for support materials for students
Explains everything beautifully. A born teacher.
Good and satisfying explanation of sigfig with objectivity rather than telling rules without context
THANK YOU SO MUCH~!!! I HAVE BEEN SO CONFUSED ALL MY LIFE AND U CLEARED IT ALL FOR ALL OF US~!! SO VERY GRATEFUL~~!! I hope your days are easy and happy, Sir ~~!!
When you said the MASS of the rock was 82 grams, I think you meant VOLUME.....
Just kidding.
I was pretending to be one of those people that feel the need to correct you over absurdities.
I'm so thankful for your videos, you're going to be the reason I make it through this semester!
You definitely made me smile. Thanks for the comment!
+Tyler DeWitt hey you look like Jesse McCartney.
Volume is measured in cubic centimeters; mass is measured in grams or kg.
GuitaRN he is just giving examples,not in reality
You had me for a minute...
This has to be the very best explanation on significant figures.
Thanks for freeing me from this haunting question
What an amazing Explanation!! This concept I'm not able to understand since high school but now it's crystal clear.
This video is really very helpful for the students to understand the importance of significant figures. Thank you very much for posting this..Bless your heart..
You are amazing sir, i have understood significant figures completely, that i was struggling with. Thanks a lot❤
thank you this was really helpful and informative and clear straight to the point,helped me for chem class keep up the good good work 👍
Excellent explanation, and having lived in Manhattan in my 20s, nice nod to the city with the super precise directions!
You explained it so simply but clearly. Thank you so much!
Good explanation. Precisely what we needed. That's significant! Thanks.
The answer to my age-old question and partially how I'm getting my chemical groove back. Thanks Tyler.
Question : Sir, shouldn't you use the word "accurate" instead of "precise"? (as accuracy is the measure of the closeness to the actual value)
yeah i think the same way
Wow finally sig figs make sense! Thanks!
this is really well explained video...you give us a veryy logical reasons why significant figures are important...thankyou sir..god bless you 😊
Thorough explanation. Impressive!
Such an incredibly awesome way to explain concepts 👌! Hats off to you
Very well explained- this helped me understand this concept immediately. Thanks so much, and please continue to make videos.
Checking in from ASU CHM114. Awesome video!
That was an EXCELLENT example!
I understood the whole of the concept becoz of just that one real life example.....do try to include examples like these....makes us understand better! Thanks a lot! may gid bless you....
You're the reason I'm starting to like chem. I owe you all of my thank you's.
That street corner analogy was beautiful, thanks for the lesson!
Thanks man, I have a summative tomorrow and I really need this.
Words cannot express how much I love this video.
Super precise explanation...🔥🔥

awesome analogy sir.....thank you.....very very much
I'm a teached. Watched the whole playlist of SF. You explain what an ambiguous numbers are, and adding them. Example: 7000 + 1
I've always been confused by this bc I'll get an answer then have to round up +20,000 or something crazy like that. How is that more precise?
Anybody watching this in 2018 and wondering why he stopped uploading videos?
KayCee McQueen 2019 haha I remover I watched him 4 yeas ago, he’s very helpful
Omg Tyler. Thank you so much. I thought I was going to fail Chemistry after the first chapter! This helps so much because I read the chapter and was like: So the F What!
such a brilliant video man. Keep 'em coming!
Thanks for making this video. Super Awesome Explanation
Hi Tyler, you are an awesome teacher and thank you for making all these videos! I only have one question about one of the words you used in this video. Why did you use the word precise instead of accurate? Based on the definitions of the two words, isn't it better to use the word "accurate" since the rocket laser scale can measure something closer to the actual value?
AGREE!
waow..this is soooo cool,am not an experience student in the science class after more than 6years studying management course,but hope this video will help me in the science faculty in my A /AS level programme ...thanks alot . Tyler DeWitt.
Awesome, Sensei keep up the good work
Brilliant technique and amazing method.
I hate Sig Figs so much, I don't understand how it would be 2.0, since 2.0*42 gives you 84g instead of 82 if you're solving for g algebraically
Thanks !
Now I get the bigger picture, exactly what was missing in my puzzle.
awesome tyler is the man! But question??? is accuracy a better term than precise for the locations downtown, since precision means close relative to other measures, whereas accuracy refers to close to true measure (like the actual location)? (which I learned from tylers other videos haha)
THANK YOU FOR TEACHING ME
Awesome explanation!
This makes a lot of sense. Thanks for clearing it up.
Hey man, awesome video. So essentially the heart of the problem lies in the fact that in chem/physics we often measure things and it is basically impossible to get a measurement that is 100% correct right?
Ooooooooh my gosh I've been so confused on why significant figures are important for so long and they've been so frustrating and this makes perfect sense
So superbly explained!! Thank you very much for this video....
You have a true soul of teacher
Wow. Thank you so much. You explained this sooo well, and I really needed to know this ty!
you're the Best maker understand guru or Teacher
Great and simple explanation.
Dr. Burger style for explaining things, great job !!!!!
You're a saviour man, Thanks a lot
What is that train noise I hear in the background between 3:00 and 4:00?
Anna R. Neligan probably a train..?
I guess. I've watched some of his other videos recently and they have the same noise, so it must be a train that passes by at regular intervals.
You sir, are brilliant. Thank you so much.
Ex: You would cut a floorboard at an estimate like 3.25 inches using the measurements on a ruler, not 3.2532419 inches.
Very helpful video. Thanks
thanks man, you explained it really well
When we estimate mesurement uncertainty in chemical measurement the general rule is that we put the final answer in only either one or two significant figures. Are we being more conservative here because some of our measurements that we used may have only one or two significant figures while others may have more significant figures?
superb explanation !!!
I learned this 31 years ago, knowing all the rules enough to get an 'A', yet I dont know why until now. LOL!!!!!! Thanks Teach!
That was truly useful, thank you so much
THANK YOU, YOU ARE AN AMAZING TEACHER!!!
I have no words. Thank you so much.
2017 BRO THIS GUYS IS awesome!!!! and HELPFUL!!! thx bro I am in high school and its the biggining of the school year u teach even better than my teacher's ur awesome:) thx for the help
