So, I was kinda ticked that I had to come home and look up box-and-whisker plots because my teacher didn't teach them, and I have a huge important test on them tomorrow, but you taught it to me perfectly! Thanks soooo much!
Man this is well explained. I am in my 3rd year and Biostatistics is one of the courses I am taking. You just made this explanation so easy I had to like and subscribe ❤❤❤❤
It's easier when 1) You have the permission and flexibility to teach it however you want 2) You don't have to keep interrupting your instruction because of behavior issues 3) You don't have a time limit 4) The only thing you have to focus on is explaining material.
It's stupid that I have to come home from class and immediately watch these videos just to get a better understanding. You should start training teachers.
Most do! sadly most students just dont pay attention or tune out half way through the explanation and then wonder why they dont understand what's being explained
Awesome, thanks! Back at 5:58, when you were saying that you would get the same value if you didn't include the median of whole set, if that is the case and you don't include the median of the whole data set, what if the number to the left of that 50 wasn't also 50.....? if it was as follows, for example: 49; 49; 49; 49; 50; 51; 52; 53; 53... where you have 4x 49's,. the median would then be (49+50)/2, which = 49.5...and it isn't 50. am I correct? I believe you don't include the median of the whole data set, hence 'INTER"-quartile, where 'inter' is defined as between. From what I remember learning, I never included the Median of the whole data set.
Remember to always include the median when making box-and-whisker plots. This video was misleading because Khan suggests you can sometimes not include it, but that's false.
You probably learn this for the first time at around 6th or 7th grade. I actually study this exact thing in university right now, at the beginning of a "Probability And Statistics" course, and I had forgotten almost all of it, hah. It's nice that university courses sometimes review stuff like this.
You do not include the median when finding Q1 and Q3. You must leave the median out of it. It just so happened that these numbers worked with using the median, which is misleading.
IQR (Inter-Quartile Range is 3rd quartile - 1st quartile (57-50=7). Outliers are values that are more than 1.5*IQR (1.5*7=10,5) above or below the 1st and 3rd quartiles. So for example if there was a value 70 (which is 57+13, and since 13 is more than 10,5 it's outside the range) it is called an outlier and is marked by an asterisk at it's position. The end of the whiskers is the next smaller number.
Teachers usually have more to teach and can't spend 13 minutes explaining it. I know my teacher spent about 2 minutes max on it. That's grad school for you though...
0:21 "A Both and Whixer Plot" I just about cracked up! But anyway, great video, as always, Sal!
flawless explanation, thank you!
Amazing Videos. A very clear explanation of the concepts. Khan Academy videos make the complicated things seem simple.
Why don't teachers teach like this????
Thank you, Khan for the amazing teaching!
Thank you very much you explained everything so perfect ..your the best Pre algebra teacher on RUclips..
So, I was kinda ticked that I had to come home and look up box-and-whisker plots because my teacher didn't teach them, and I have a huge important test on them tomorrow, but you taught it to me perfectly! Thanks soooo much!
I want to thank you so much for the help. Seems our school system has no clue how to make her understand this math. I would be lost without this.
Man this is well explained. I am in my 3rd year and Biostatistics is one of the courses I am taking. You just made this explanation so easy I had to like and subscribe ❤❤❤❤
You take the 2 numbers add them divide them by 2
Thank you khan academy!!!!!!!!!!!! In class I wasn't getting these, but you explain thing so well thanks Soooo much
This is the third video I watch with this professor. I WISH HE WAS MY TEACHER!!!

It's stupid that I have to come home from class and immediately watch these videos just to get a better understanding.
You should start training teachers.
It's very well explained. Thank you.
Thanks, My Algebra EOC is tomorrow so this really helped.
praise Allah, from Osama in kuwait
Thank you! I am not good at math so I use your channel to help me! :)
thanks for the help, also joined your website
Thanks for the video, made revision a lot easier.
Man i never comment to RUclips videos...but i had to do so here
THAANNKKK YOUUUU !!!!!!!!!!
Most do! sadly most students just dont pay attention or tune out half way through the explanation and then wonder why they dont understand what's being explained

this was my math homework to watch this video
GOD BLESS YOUR SOUL
saved me on my test THANK YOU
Thanks Helped Me Alot !
Thanks! You made this seem so easy now!
thanks so much(: I hove trouble paying attention in class so this was really helpful! (lol, most of the time i just choose not to)
thanks khan u helped me understand them
thx so much this has been so helpful :)
YOU MY MAN ARE AWESOME
thank you
Thanks for ur help !!! :)
This stinks more Then a donkeys butt joking this was amazing thank you I would have never been able to do my math homework without this 😅🙂
very well explained thx
Really useful! Thanks
Thank you this helped a lot with my HW
oh my god thank you so much i really appreciate it
THANK YOU SO MUCH... damn only if my professor was this good
thank you so much you just saved my grade :)
You're a much better teacher than my teacher. You should earn my parents' taxes.*
Thanks.
he got Q1 and Q3 wrong - its supposed to be the 4.5th score of that quarter. he has the right number (it doesnt change) but he used the wrong formula
oky so now i understand thew lowest quartile and the highest quartile thank u so much for the help
This really helped me for my test! Thanks! :D
Mention of outliers would have been useful
AMEN !
thank you your great !! you helped so much
at the beginning it sounds like the 'wheel of fortune' tv show lol
he forgot to mention greatest and least numbers
this helped alot
didnt get it in math class
now i do
lololol
Who's watching this in 2019 😂(Thanks Khan Academy)
Thanks alot man this really helps
your gonna help pass my GSAT!!!!!!!!!
@animatorization, it's 34.5 :) because that is in between 34 and 35
Bravo! this video must be designed so three year's old students can understand it :)
Remember to always include the median when making box-and-whisker plots. This video was misleading because Khan suggests you can sometimes not include it, but that's false.
looks more like a traffic light. Let's change it to the traffic light diagram.
very helpful
Thank you kahn. You da bomb
That you so much! :)
i love your voice i wanna marry it!!!!!!!! sorry i love voices.
What grade is he supposed to be teaching? I'm in 7th grade and I'm learning about this and damn he teachers better than my own math teacher!
I'm in 6th and same! My teacher has no idea what he's talking about compared to this guy
You probably learn this for the first time at around 6th or 7th grade.
I actually study this exact thing in university right now, at the beginning of a "Probability And Statistics" course, and I had forgotten almost all of it, hah.

thanks this really helped
waaa thanx u!!~*
i really love your explanation
this was very helpful for me!!
Your Q1 and Q3 in this video is wrong... you don't include Q2 when calculating the other two quartiles.
label it and give it a tittle tooo
Sooooooooooooooooooooo much help thanks Khan Academy
thanks khan
How many numbers are inside of each bracket?
You do not include the median when finding Q1 and Q3. You must leave the median out of it. It just so happened that these numbers worked with using the median, which is misleading.
UR AWESOME I ACTUALLY UNDERSTAND
@themomo6710 i guess u include the actual median too? i dunno, good question though
this helps alot thx
I love you khan academy
great
Really different how I learned it
good!
This was helpful but you forgot to talk about OOUTLIERSSSSSS!!
this was verryyy helpful!!!
Thanks
What about outliers though?
Outliers are just marked on the outside. If they are less than the lower fence and greater than the upper fence then they are outliers
Sabrina Collins moderate/mild outliers are beyond the inner fence but within the outer fence, servere outliers are those beyond the outer fence :)
IQR (Inter-Quartile Range is 3rd quartile - 1st quartile (57-50=7). Outliers are values that are more than 1.5*IQR (1.5*7=10,5) above or below the 1st and 3rd quartiles. So for example if there was a value 70 (which is 57+13, and since 13 is more than 10,5 it's outside the range) it is called an outlier and is marked by an asterisk at it's position. The end of the whiskers is the next smaller number.
What if they're the same numbers? I mean like the median between 53-67 if that 57 were a 53 as well would it just be half a box?
why do you add one to the numbers? (17 +1) / 2
thanks really helped
Oh my god you saved my algebra grade. . . thankyou
Teachers usually have more to teach and can't spend 13 minutes explaining it. I know my teacher spent about 2 minutes max on it. That's grad school for you though...
I have watched this 4 times and I still don't understand
