5 years later and I’ve never used a stem and lead diagram once in my life lol

[@Aisha-gd6dq]

I’m in a middle of a math test rn thank you

[@zestylemons7771]

Did you pass

[@cricinfotv9945]

you cheating

[@sabading]

thank you so much for this information my add maths textbook shows how to do it but I didn't understand shit..I come here and 2 mins into the video and I now understand the stem and leaf diagram thank you so much...

[@rahulkalansooriya5808]

Same!

[@YeslinMyPerfectSkin]

Omg!!! Thank u very much!!! The book gave me a headache but u explained it so easily 😭😭😭

[@joshdaltonug4938]

This has been so helpful to me especially on calculations of range, determination of mode, median and interquartile range

[@rahulkalansooriya5808]

The way u showed it is wayyyy easier than our teacher and book!

[@stevecollet9884]

Very helpful thnks a lot now i can proceed as i prepare for my HSC exams ☺

[@andreeap7393]

Thank you for the accurate explanation and the variety of numbers chosen.

Ancient knowledge can reveal so many answers to so many mysteries. In this case, the mystery is mathematics. And the ancient knowledge, is from 8 years ago.

[@jamesnizzy9774]

Your the only maths teacher on this platform that does not confuse me, a sub and a like earned!

[@igneousyt6817]

Jammyjamboy u need an english teacher.

[@ButtChinsAreHereToStay]

Stem & Leaf is one of the easiest topics in maths so that makes it hard to get confused in the first place. There are many great maths teachers on this platform. Hegarty & Wright would be in my top 3 for starters. If you haven't heard of them just pick a random topic (or a GCSE past paper) & they will be near the top of the search.

This man is best.... honestly because of him i did my online test

[@bryanmoumou689]

Multimodal and left skewed!

I'm in year 9 this helped so much thx my G

[@Airenifinity]

How did you choose the 21 as key?, why u didn’t pick the 31,40 or any other? Is it gonna be specific 21? I’m confused what should I put for my key

[@cyumusic]

The key can choose any of the numbers?

[@taps8017]

Ya thanks I appreciate it man you may of just helped me in my summer exams

[@beststar7725]

Thanks for simplifying this..really grateful

[@davidandangel1053]

thank you you helped me so much i have an exam on Wednesday thank you ❤😊.

[@shinestars2595]

Very well explained. Awesome sir

[@teatualasi5676]

Great video bro. It helps a lot but I think you were wrong about the skewness of the data. It supposed to be skewed to the left not to the right. Construct a box plot using the five number summary for a clear picture of the skewness

[@khanyisilendelu2696]

Excellent lesson Mr Anorld

[@SonnyJim-re6rc]

Thx so much this rly helped me out

[@sasiruherath59]

great. explained very well. I couldn't understand anything my teacher said.

[@rakeshchandra9115]

Really helpful thanks man.

[@annatan5228]

how are you supposed to know what number to find the median?

[@yusufdadkhah7561]

@anna Tan, for exact even amount of numbers given, the median, is literally the middle number, there are exceptions when there are uneven amount of numbers given does not have an exact shown middle number, for those types of sets, add up the middle values and divide by 2. for when the amount of numbers given does not have an exact middle number add up the middle values and divide by 2.

[@derekphoenixz7271]

thanks for explaining the interquartile range !!!

[@agby945]

Thank you!

[@noora3408]

another method for the range is n ( no. of data ) which in this case is 15 + 1 ÷ 2 which is 8 method : n + 1 ÷ 2 and to find the place you can count the answer you got ( 8 ) and you'll get : ( answer down below )

[@noora3408]

8.1st place ( 1 is the place ) hope this helps and thank you sir for this great effort you have put in this video that helped many of us 😀😁😊 ~ Noora

[@noora3408]

that is one of MY examples please dont get me wrong or get confused

[@athulabar1]

Very Nice...

[@genettiruneh5775]

Nice explanation!

[@shahidarazak3402]

Excellent Teaching!

[@iNahidkhan]

Thank you matey

[@danielogunsalu7140]

appreciated

[@Ohmyitsmal]

can we take any number for key which is within the data given? suppose here can we take 3/6 means 36 instead?

[@yusufdadkhah7561]

@Malsa Muj sure as long as it is true, it would help if the terms you use are misleading in the diagram and you properly defined those terms to what you mean to get rid of possible confusion and to make everything easy to understand. we are not supposed to do fractions=the numberator+the denominator, instead if need be you should put 3/6ths of 76 is 36,since 13*6=78 and 72/6=12 and 12*3=36. you should be doing this kind of specifying when the values of total or some amount you have equals 76 and you would like to represent it as a fraction.

[@ziids2393]

don't you count along 15 from each side because there is 30 number so the mode would be 35. We've done this in class and the teacher said if numbers appear the same amount of times like 44, 44 and 55, 55 then the mode would be 44 and 55

[@yoloypuri8674]

Crazy Gaming03 You can't have 2 modes or plus

[@naomia2311]

Yh that's how I learnt it aswell

[@kurama4172]

You'd have have to divide it by 2 to get one answer

[@bernardben6]

Legend thanks. The only thing I didnt get was the key now I know thanks bro.

[@tauheedmuhammad4512]

Thank you brother!

[@LOLO-zl2or]

Is it skewed right or left? I was told if the tails were left, it was skewed left and if they were right, then it was skewed right. I am a novice so please clarify. Thank you.

[@freakychannel123]

ya it's skewed to the left! The tails on left side

[@arny85]

If it's tails off to the left we say it is negatively skewed as it tails off in the negative direction. If it fails to the right we say that is positively skewed. Hope this helps.

[@mariashiavi4910]

+David L.L. skewed to the left!

[@TheParthB]

if its in between 15 and 16 then there will be the same amount of numbers on either side of the median, whereas, if between 14 and 15 then there are more numbers on the right of the median than on the left of the median

[@johnshootersniper6658]

Can I ask something why did u divide by 2

[@Yuhboiichrislitty]

So The key can be a random from the numbers we are givin from the steam and leaf chart

[@dfors17]

Where do u get the 2 from

[@teachergloriacallenderspri5485]

Well explained thanks

[@olerilemaome2206]

Excellent Explanation!

[@gachaoparchie8908]

Thank you man awsome video

[@elodieballarin1781]

can someone please explain to me why the key has to be 21? Like how do u know what number the key has to be

[@wilby3196]

@noahyesnoahayehes it doesnt have to make sense lol

[@mathemagixlearningsolution876]

This data set has more than one mode. It is Multimodal.

Helpful thanks

[@radhagopal9009]

This really helped

[@ibraheembaloch9772]

how did you get the scale\

[@nb9916]

Ibraheem Baloch Baloch gang

[@yusufdadkhah7561]

we get the numbers on the left of the diagram from the order of things to calculate, i.e: 1. range 2. mode 3. median 4. interquartile range we get the rest of the numbers from the sets and in this video the guy put 1 digit of a 2 digit number number and put it on the right of the black line. it is wrong to cancel 1, 2 digit numbers and only put the first number, everyone is supposed to write the whole number on the right of the line after cancelling it from the set of data. the line was printed on it, you can put the line there through the software called word and print it off.

[@soumiroychowdhury4609]

really very helpful...thanks

[@josephconte5491]

Thank you

[@JUNGKOOK-lx7kt]

How do you find the key??? I didn’t learn this because I’m absent send help

[@annastevo4042]

In the question it will include a key showing how to read the numbers if thats what you mean?

[@josephconte5491]

Isn’t for the last question 99 the mode

[@FaTalTurban]

thank you

[@abpointofhacking3041]

helpfull thnks very much

[@footballfan5442]

The only thing i dont understand is the key. Plus this is something new to me as i am in year 9. Plz help.

[@nefaraiu]

you’re in year 12 now wow

[@wilby3196]

HOW DONT U GET IT IN YEAR 9 my boy we study it in elementary

[@mischievoussheldon6952]

but why is 21 the key

[@alexmatevo6372]

Thank you bro.

Bad Boy not even close

[@smileyface6727]

He is Irish I’m Irish ik

[@geoboy700]

Alex Irwin hehyyyyyy

[@derrick4525]

i think the last part median it was wrong because you met to do 67 divided by 32 = 2.09375

[@secra1975]

This is not a good video because he makes the comment that there is No Mode to the data. The definition of a Mode is a number that happens the most that occurred more than once. In the set there were many numbers that occurred two times or more. He chose the lazy way and instead on making a large list of Mode's he chose to say there was No Mode which is BAD information. I do want to say though that his use of a Key is a great way to interpret this data and is a GOOD point to add to the information when teaching this concept.
