Thanks for stopping by. Today we are going to talk about the difference between accuracy and precision.
Accuracy and precision help inform our knowledge when taking measurements.
Accuracy refers to how close something is to the target or actual. Using a target to illustrate, consistently hitting near the center would be accurate. Using another example, if we were to use a scale to weigh a 20kg dumbell 3 times, and the scale read 18.95 kg, 21.22 kgs, and 19.81 kgs for each respective weighing, we would say that scale is accurate.
Let’s jump to precision and then we’ll bring it back together.
Precision refers to how consistent our results are, regardless of how close to the true value they are. Using our target example, if we hit this area of the target on every shot, then we are precise. Using the scale and 20 kg dumbell example, getting measurements of 23.11, 23.09, and 23.12 for the three trials would tell us our scale is precise, just not accurate. It’s consistently inconsistent.
So, a quick review and comparison. Accuracy is measuring near the true value. While precision is getting consistent measurements or results.
Let’s use the target for some more examples.
This would be accurate and precise. All the points are close together and average around the true value.
This would be accurate but not precise, the results are around the true value but not too consistent with each other.
This would be precise but not accurate. All results are close together but not consistent with the true value.
And finally, this is neither precise nor accurate, this is pretty much how it looks when I’m shooting, no consistency, not equidistant from the center, just random.
It’s important that measuring devices are both accurate and precise, whether it be in research, construction, engineering, or even in your home. If they are not, then results from measurements will be misleading leading at best and fatal at worst.
I hope you understand accuracy and precision a little better know. Comment below if you have any questions. And subscribe for more educational content.
I’ll catch you next time.
Finally cleared my doubt. Loved this explanation ❤❤💃
I'm glad I could clear things up for you!
@@2MC ❤️
Safe to say this is an accurate vid
I see what you did there 😉
Lol
Precisely
haha
Haha! 😂
This video offers a precise definition of accuracy and an accurate representation of precision.
Copied but okay
This is better than the Ted-Ed video on the exact same topic. Well done man. I especially appreciate the last part where all four scenarios are clearly illustrated. Thank you. You have a new subscriber.
Wow, thanks!
@@2MC Agreed. I just watched theirs before this one, and now I will be showing this video to my class. Thank you!
Thanks I’m in my chemistry class right now and we were told to scan a qr code and this was the video
That is awesome!!! Thanks for sharing and thank your teacher for the support 😍
no way. i’m in chemistry class rn and we scanned a QR code and this was the video🤯
I have struggled to understand this in class but i wasn't expect that I will understand yours more clearly, thank you, Mr.!
You're welcome.
I don't usually comment but this video was VERY HELPFUL. Your explanation was easy to comprehend and it clicked right away. Best video on Accuracy vs Precision, period! Thank you so much for this MASTERPIECE -your hard work is genuinely appreciated. 😇
Wow, thank you for your kind words. I'm glad you found it helpful!
@@2MC No problem
this was one of the most helpful videos I have ever watched👌

@@2MC it is very helpful thanks alot
i subscribed
This video was made in 2017 and he's still replying to comments in 2021. Mad respect and thanks
I try to keep up, haha.
Watched 8 min video .. I didn't get anything .. but ur video is just 2 min and u delivered everything ... RESPECT 100+
Very well put together, informative, and quick video. Much Appreciated!! Subscribed!!
Thanks for the sub! My goal is to create well put together, informative, and quick videos.
Came here from that confusing video from TEDed. Your explanation is a lot easier to understand. Thanks
ABSOLUTE LIFESAVER! Explained better than my science teacher❤️ keep up the good work!👍
I'm having an exam tomorrow, This helped me finally understand Accuracy and Precision.
Gotta go continue my studies-!
Excellent, I hope your exam went well.
@@2MC It did!
It was so confused about accuracy and precision , I really can't understand the difference between the two , I'm so greatful to you because it was a simple explanation and it cleared all my doubts . Thank you so much ❤️❤️🙏
this video is accurately precise for me!
💯
This video saved my butt! My teacher just has a way of making things more complicated. Glad I found this video.
This video was precise and accurate to my logic and understanding thankyou
Wow .. I've been trying to learn this concept for over a year and you just made me understand it in minutes
This was so clear and concise. Very helpful. Thank you.
Glad I could help.
Its amazing how I have a clear concept just by watching a 2 minute video! Thankyou!
I have seen lots of video regarding this topic but I was unable to understand this clearly but now I found ur video and cleared my all doubts so thanku for the explanation .
😂😂😂 I clicked on my assignment's link and I got redirected here. But to say this pretty much an accurate video and truly helpful
Glad it helped 😊
@@2MC truly bro a big thanks. This topic now became my forte bro😂😎
This has to be one of the explanations of the difference between the two I've seen since my introductory engineering class in college.
After going through the notes for 20 minutes still having accurate knowledge but after your vedio my knowledge is precised
Well said 🔥
I really enjoyed the teaching explanation
This is the easiest way to explain this, thank you.
i have an exam tomorrow and this helped me a lot way more understandable than the ted ed video❤

Helped me understand these topics before my exam. Thank you
Got that topic clear👍🏻
Yay!
Perfect for those who have limited time to learn 😊
Thanks for helping me in my physical science test
Our teachers gave us the same example but i didn't got that!
Today i succeeded 🎀
Thanks!
Great job!
