Introduction to Accuracy and Precision (includes Relative Error)

This video includes the definitions of Accuracy and Precision. It also shows several examples using a "Safe Dart" bow and arrow. It ends with the equation for Relative Error.

0:00 Intro
0:44 Definition of Accuracy
1:39 Definition of Precision
2:17 The Question for all the Examples
3:48 1st Example
4:31 2nd Example
5:14 3rd Example
6:33 4th Example
7:32 Relative Error Equation
9:37 "Safe Dart" Outtakes
(it took forever to get the "Safe Dart" to work)

The end of this video explains his excitement for everytime it stuck, much more impressed now

[FlippingPhysics]

As the creator of these videos, I wholeheartedly agree. Thanks.

SO MUCH HARD WORK FOR
YOU ARE AWESOME SIR

[bernardoferreira]

you are a m a z i n g. i wish i had you as a teacher at school. anyway... i suppose i can say that you are my teacher now, and a better one than any of those that i ever had! i am so glad i have found your channel, i want to be able to one day to say to myself that i've learned everything you had to teach in all of your videos, because i really want to see them all. i wish this had more views. it is obviously true that you put a lot of effort in this. thank you so much, in other words! cheers from portugal!

I LOVE YOUR CLASSES, AND HOW YOU R GENUINELY TRYING TO MAKE LEARNING PHYSICS FREE!!! WHAT I LOVE SO MUCH ABT THIS VID IS THAT U R SO HAPPY WITH THE ARROW SHOOTING, AND I JUST FELT LIKE HOW FUN OF A IN PERSON TEACHER U WOULD BE, DOING EXPERIMENTS WITH US!!!!

[WeAreShowboat]

Cool idea, having "students" to talk to and trying to make the video fun, and making it real with the actual darts.

[chopin]

Legit one of the best physics playlists ever.

[highpickout]

Omg the effort u put in this video is so awesome . You are God of physics

[LadyofStarlight]

The first video that I've ever seen.. It's a shame that Edpuzzle cut out the blooper portion of your video.

He deserves so much more.

P.S. Btw I have a feedback for you, maybe our temperaments do not match but it would be really helpful if you repeated the words again, like after teaching a concept or reading a line, could you please repeat the line? I know it would make the video a little long but we are not rational, we are emotional people. This trick could really help establish more rapport and help us get into the concepts imo. Really great video!

[blackout_robotics]

No wonder he was so happy when he hit the board through the video.

[CentFlip]

What do you mean by using the lecture notes responsibly?

[Miranzinha_the_miranha]

when i reached the end of this video, I knew why Mr. P was so happy in the beginning

[thebassofmontecristo]

"That's how cool I am."

Bo's XD

[Anveshkrishna]

I didnt understand number 3. Do we always calculate the avg and determine how accurate our measurements are?

[phantomserhat]

I noticed that you were always looking at the top side of the screen. I think you read your speech from a screen or sth like that, am I right?

[cassieknight]

At the 8:45 mark I could not take anymore. I know you can do better ... Remember, I, (and perhaps others), need to override my previous attachment to the meaning of precision vs. accuracy.

[Nitstar]

Actually, I disagree when people use high/low in their problems. They are 100% relative. I am saying this because you used this in your problem.

[athenawheatley]

If you're coming here from Edpuzzles, answer to first question is Low Accuracy & High Precision. It should be obvious if you can view the image, but for anyone who can't, here you go.
