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!
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.
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 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
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.
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.
When finding the median of the 1st and 3rd quartile, do you ALWAYS include the median of the 2nd quartile? Or does that only apply to an odd number of data sets?
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.
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.
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...
Thank you very much you explained everything so perfect ..your the best Pre algebra teacher on RUclips..
omg....that's super awesome...! :) i was failing my test before watching this video..! thnx alot khan sahab..!
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 really like this kindof plot style, nice and intuitive.
Why don't teachers teach like this????
Thank you, Khan for the amazing teaching!
Thanks for the video, made revision a lot easier.
Your an excellent home school teacher!!;)
This is the third video I watch with this professor. I WISH HE WAS MY TEACHER!!!
i studied this in the beginning of the year thx man ur the best

Only video on youtube I have ever seen that has no dislikes xD
this is one great video
thanks, your videos usually help me a lot!
thanks for the help, also joined your website
0:21 "A Both and Whixer Plot" I just about cracked up! But anyway, great video, as always, Sal!
Khan is by far the best teacher on youtube!! :D The rest confuse me...
I like the many colors it help me understand better.
Very nice explanation. Thank You!!
lol, omg my teacher spent an hour explaining this and I didnt get it at all, but you spent 13 minutes and now I get it completely!
Man i never comment to RUclips videos...but i had to do so here
THAANNKKK YOUUUU !!!!!!!!!!
flawless explanation, thank you!
Thank you! I am not good at math so I use your channel to help me! :)
Thank you khan academy!!!!!!!!!!!! In class I wasn't getting these, but you explain thing so well 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 ❤❤❤❤
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.

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.
Amazing Videos. A very clear explanation of the concepts. Khan Academy videos make the complicated things seem simple.
How many numbers are inside of each bracket?
You take the 2 numbers add them divide them by 2
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
But what if you have 2 numbers in the middle?
you add both of the numbers and divide by 2.it doesn't matter if you get decimal numbers its still your median
saved me on my test THANK YOU
what program are you using?
@themomo6710 i guess u include the actual median too? i dunno, good question though
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.
@animatorization, it's 34.5 :) because that is in between 34 and 35
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.

This helped alot for studying thanks
why do you add the 1?
Thanks, My Algebra EOC is tomorrow so this really helped.
Thanks Helped Me Alot !
where are the outliers ??
anything lower than the lower quartile - 1.5 x interquartile range. Or, anything higher than the upper quartile + 1.5 times the interquartile range
why do you add one to the numbers? (17 +1) / 2
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.
what program is this that khan is using? did he create it or did he download it?
thanks khan u helped me understand them
thank you so much you just saved my grade :)
It's very well explained. Thank you.
waaa thanx u!!~*
i really love your explanation
this was very helpful for me!!
THANK YOU SO MUCH... damn only if my professor was this good
oky so now i understand thew lowest quartile and the highest quartile thank u so much for the help
very well explained thx
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?
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
i love your voice i wanna marry it!!!!!!!! sorry i love voices.
Thank you this helped a lot with my HW
thx so much this has been so helpful :)
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)
does anyone know what program he is using?
Thanks! You made this seem so easy now!
This really helped me for my test! Thanks! :D
YOU MY MAN ARE AWESOME
your gonna help pass my GSAT!!!!!!!!!
oh my god thank you so much i really appreciate it
When finding the median of the 1st and 3rd quartile, do you ALWAYS include the median of the 2nd quartile? Or does that only apply to an odd number of data sets?
Michelle Le You only include min q1 median q3 max
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.
This definitely helped. Thanks
Kosts Too Much ;)
Really useful! Thanks
what if you're trying to find the 1st quartile and it's a even number like between 34,35 which number is the 1st quartile?
thank you your great !! you helped so much
Thanks for ur help !!! :)
GOD BLESS YOUR SOUL
thank you
Bravo! this video must be designed so three year's old students can understand it :)
Thank you kahn. You da bomb
this was my math homework to watch this video
Mention of outliers would have been useful
looks more like a traffic light. Let's change it to the traffic light diagram.
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 😅🙂
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.
It's nice that university courses sometimes review stuff like this.
very helpful
Thank you but you do not include the median (that is what my math teacher said)
Maybe your teachers wrong.
Actually, through out the entire vid, he says that 53 is the median. There is also an arrow pointing to 53
Dat Epicness Nerd
Thanks alot man this really helps
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...
label it and give it a tittle tooo
this helped alot
didnt get it in math class
now i do
lololol
thanks this really helped
he forgot to mention greatest and least numbers
what program
Oh my god you saved my algebra grade. . . thankyou
this was verryyy helpful!!!
You're a much better teacher than my teacher. You should earn my parents' taxes.*
Your Q1 and Q3 in this video is wrong... you don't include Q2 when calculating the other two quartiles.
This was helpful but you forgot to talk about OOUTLIERSSSSSS!!
Who's watching this in 2019 😂(Thanks Khan Academy)
thanks khan
Thanks.
UR AWESOME I ACTUALLY UNDERSTAND
I have watched this 4 times and I still don't understand
That you so much! :)
