Accuracy and Precision

To see all my Chemistry videos, check out
socratic.org/chemistry
This is an easy to understand introduction to accuracy and precision. We'll play "guess my age," and look at bulls eyes representation of accuracy and precision.

Hey everyone, I'm here to help. If you have any questions or just want to learn more, click on the link in the description above. It'll take you to a page where you can ask me questions.

[@tdewitt451]

@t50n oh yeah, also watch my video "error and percent error," which also talks about what you'd do if you made a bunch of measurements that had different amounts of accuracy and precision. and thanks for your good question--it will help me make the videos better in the future.

[@mistymochi1258]

Sir ur great 😊

[@tewtz]

This shit makes so much sense to me now. Thank you, we NEED more teachers like this

[@bluknight99]

Dude! I'm a 45 year old cop finishing my bachelor's degree (FINALLY) and I'm taking a science lab with this stuff (accuracy, precision, significant digits, etc...). I was feeling like a complete idiot until I found your videos! You, Sir, are a life saver!! THANKS!!

[@ComandaKronikk]

Good on you man, you must well and truly finished by now!

[@FreeStateMarc]

I hope you found something more honorable to do. #bluelivesmurder

[@FreeStateMarc]

Arrest me, boot licker. The police force was made as a monopolized investigative service and protection racket. It has taken generations for them to evolve into a militarized force that terrorizes the people who they're sworn to protect; those they see as enemy combatants. Bunch of brownshirt, evil statist fucks you are.

[@expiredclan4473]

LOL somebody watches too much CNN XD @freestatemarc

[@AidanChilds]

@@FreeStateMarc dude was just trying to learn physics, relax

[@Ghost572]

I actually forgot about this channel for a while as I've been studying other things but as soon as I saw it I remembered how good of a teacher this guy is.

[@krishnannarayanan8819]

Same!

[@tdewitt451]

@t50n good question! you use accuracy and precision when you're doing measurements, like in the lab or something. like maybe you're measuring the amount of gas in a balloon or something, and each person gets a slightly different answers. you want to be able to find out how accurate and/or precise your answers all are. make sense? in the second video "Accuracy and Precision 2" i show more about how you'd actually use this in a real world lab setting.

[@monukeys1105]

Sir you are helping me alot !! I cant imagine my chemistry without you this year !! I love you so much ! You are a great teacher !!

[@chesshirecattto_o2895]

Thank you so much! I like your teaching style!

[@iamahmednahian]

Mr. DeWitt, you aced the teaching part here. Your friendly way of explaining worked towards my understanding of the topic. Thanks a lot. Please, keep it up. :).

[@Abominatrix650]

I wish my teachers were a bit more like you! You are a brilliant teacher - you explained it well and I paid attention which is uncommon for me! Thank you very much! I hope you live a fantastic life and (when you eventually do arrive there) have a brilliant afterlife!

[@omi5137]

I've watched various videos and read lots of texts to understand this concept, but only this video did it for me!

[@peterchish3600]

Man u are the best 11 years later I can still learn for u I hope you are alive u the best

[@lincybiju9969]

Wonderful.. after going through many videos .. this video really taught me what accuracy and precision is .. i luv it .. wonderful way of explaining .. keep it up

[@ajitsingh-cm9il]

U r actually a GURU. u know how to explain things. nice explation. keep it up

[@tdewitt451]

To learn how to do this, you want to watch the video called "Error and Percent Error."

[@laamandamaria]

THANKKK YOUU I have a chem test tomorrow and you just saved my life!! :)

[@l0vexaile]

thank you so much! this helped out a lot! i was trying to learn this but i couldn't get anyone else's explaination but i get yours very well! really helped me in doing my prelab :D

[@emmabell529]

Thank you so much! My teacher is so confusing but this made it simpler. Thank you!

[@meyosheTUBERS1]

BEST CHEMISTRY TEACHER EVER I WISH MY TEACHER TAUGHT LIKE YOU THANK YOU

[@abdurrahmancetinkaya5480]

you're better than my teacher and your explanation is perfect.Thanks alot

you are the best man .i did not get any video near to this .thanks

[@mohammadorabe8589]

Your explanation is amazing! Thanks.

[@natassiacorrea7249]

Thanks for the video Tyler, really good explanation!!!!!

[@nitindev1920]

While calculating process capability of a machine, with your video i came to know that Cp is precision and Cpk is accuracy, Precision requires more investment than accuracy. As the precise process can be shifted to achieve results. Thanks

[@KaylynMichelle04]

He make it so simple ! It make so much sense ! Thank you 🥰🥰

[@nhokcon245]

thks alot for all the videos u upload on here. There are a lot of videos that helpful to us. Hope u will make more

I have an idea for my teacher's activity for tomorrow :)) thanks again.

[@SergioRomero-ge9tx]

Great video. Thanks man

[@calpoop]

what would it look like for a dataset to be imprecise yet accurate? is it something like a work of art in "negative space," where you give all kinds of crazy disjointed answers that somehow perfectly carve out the center?

[@mr.friendly857]

Thanks alot man,now i got the concept :)

[@themountaingirl5024]

Nicely explained

[@amahlediya2934]

I was preparing to write a test.but jhooo you did it for me 😍🤭I didn't even go back to my notes.thank you🙌🥰

Wow I got it nice video bro helpful
At 1 st I tought like you are a science teacher and you are going to take a class about this but I like the way you delivered

[@kash946]

thanks 2 u buddy u have very gud method of teaching .......... just be happy

[@subhankarpramanik2108]

Sir,
If true value is suppose 1.5 and one set of trials are 1.3 and 1.9 and other sets are 1.6, 1.6, so which set is more accuracy ?

[@fluid3319]

1.6

[@priscillalk5324]

Thank you so much Sir🙌
You make failing so impossible 🙏😊❤️

[@ab0oo0oo0d]

Thank you very very much
that's really helpful

[@yenpham6754]

THANK YOU SO MUCH!!

[@asimfaiz3039]

so good very easy to understand

[@nucleus7896]

Amazing video!

[@jakeriadison5257]

so helpful , im a sophomore in highschool in my freshmen year of college

[@Josh_Lev]

This is a great video!

[@user-xl6tm5mx7g]

Hi Tyler, I wonder about the last example of not precise and not accurate. None of the individual measurements ae accurate but when you average the four very imprecise and inaccurate values they aren't too far from the true value. So is it entirely true that they are inaccurate?

[@jolianalim1600]

Thank you so much for this video !

[@saintisraelmedi7686]

You back (biochem)👏🏽

[@KatiaGyetvai]

You are amazing! Thank you!

[@naseralhamwai7627]

We need you to do videos about uncertainties!! Please do so...

[@Stephane1750]

What about a 4th situation where measurements are not precise but accurate?

[@michellewitczak2410]

Wow very good explanation thank you!!

[@mimomimo6994]

You are wonderful teacher from 🇪🇹 thanks

[@HasibYouTube]

Really helped ty

[@dayni2839]

Finally I understand this concept

[@wandering-with-wonder]

YAY I GOT IT THANK YOU SO MUCH SIR!

[@maielkady2570]

Excellent video 👍

[@sara-nk6uq]

excellently taught ...

[@chittibabuadatravu5538]

Good explanation

[@laithazzam5322]

first of all.... thank you very much....I have a question.. what if one of the four people in 5:35 guessed that the age is 30... would it still be not accurate???

[@Asad-wp5pc]

yo I have the same question to lol

[@miguelalcantar935]

It depends on the rest of the values but I would say no

[@jovanrodriguez7796]

Your channel photo is badass

[@kaybaye7628]

I feel so much smarter thank you so much

[@josikarustagi1147]

what is accuracy and precision of the numbers 750.5 and 0.00002932.

[@santislayz1089]

You Sir, are good!

[@Mynguyen.24]

Thank you so much!!!! REALLY HELP

[@zahirullahwazir5853]

You are wonderful!!!!!!

[@itamaratyirbr]

Thanks a million!

[@antu4581]

great ,good lessons

[@VictorBravocarsales]

Jesus Christ sitting on a park bench, this guy is amazing!! My chemistry is an accelerated course, so my professor doesn't have the time to teach us everything. I would be so lost without your channel. Thank you sir!

[@kattoljet4750]

thanks so much !
