I know it’s six years later but THANK YOU SO MUCH.
I was ill when we covered this topic and now I’m reviewing it for homework and no one sent me notes so I’m currently doing my own. No textbook was able to make it as clear as you did. Thank you!!!!!

You are a life saver, I’ve always gotten confused with how to find cumulative frequency-now I’m confident to say I’m prepared for my mock exams

I know this video is 6 yrs ago .. but i litterally wanted it now as hell .. so helpful .. thanks for the support 🙏

Even tho this vid is 7 years old thx so much

[@tooth5276]

Do your answers matter on how you draw the curve because i got different answers

[@simaalmutlak7744]

I'm not sutre if its me or you,but the points are plotted wrong.Like I don't know how to plot the points its never accurate and theres a median question where its not the same as u did?

[@amjaazali4815]

It's my O levels in 2 hours. Thanks!

[@birdie7344]

how'd it go?

At 5:00 ,isn’t the median 34.5?

Thx

Thanks🌷🌷🌷

[@thitsarkhaingwo236]

I dont know how you calculated the median ..

[@brendenperera8283]

Thank you!!!!!

[@RR-bq7tm]

The median won't be the the numbers divided by 2

[@finanderson4678]

Sick vid fam

[@andaleenfatima3590]

Thank you I have my maths gcse exam tomorrow and forgot how to do this!

[@abdelrahmaneldobosh9850]

I still dont understand the interquartile at 5:47

[@joacomiguens4493]

Al menos no tenes una heladera rota

[@blitzedoblivion4280]

Sounds like zerka

[@ayachammout7013]

the median is equal to the sum of the frequency divided by two , but in the first question it was 30 , and the sum of the frequency was 50 , it should be 25 , right ??

[@LEA_-_-_]

Bro I'm also baffed about this

[@LEA_-_-_]

Did he make a mistake ?

[@abdulhakeemmowoe847]

How did he get the frequency

[@karammann9798]

It was already there unless your on about the cumulative frequency which is all the numbers before added on to the current number

[@amaacooking961]

Do you math 3:15

[@maheenFahad]

gahh dang thx for the explaination

[@elitesnips2197]

aint last question 15 people? cause it goes up to 70..

[@elitesnips2197]

*10 seconds later* i understand..

[@HattieMcDanielonaMoon]

Omg I had no idea it was this simple I lost 5 marks on mocks for no reason UGH

[@chrysanth267]

Wish you could filter out all the, "Thank you so much this was great", "I didn't understand this when my teacher taught it but this was perfect!", "Great Video!". That blocks up every single UA-cam video.

[@bananess_]

why?

[@alraydalley5635]

How did you get the median

[@alraydalley5635]

Also the inter quarter range

[@marcelr4007]

Half the total frequency and draw a straight line, on the value, on the graph, until you get to the curve then draw a line perpendicular to the point and you can find the median.

[@marcelr4007]

@@alraydalley5635 For interquartile range you have to find the upper quartile and lower quartile and find the difference between them(UQ-LQ). To find the upper quartile you times the total frequency by 3/4 then plot it on the graph as if u were finding the median but instead finding the upper quartle, and for the lower quartile you do total frequency times 1/4 and plot on graph as previously.

If Noone got me the mathsgenie guy got me can I get an amen 🙏🙏

[@raywong401]

Hi, since in this video the data started from 0, that's why you joined the curve from (0,0). But what about if the data started from 1 for example, do I start from (0,0) or (1,0) or from the first point plotted?

[@youtubelife921]

It’s optional, you either start the line at 0,0 or at the point where your data starts

[@ebunarowolo7091]

the median should be 47

[@flameify8285]

Ikr

[@damnthatscrazy32]

🐐

[@raindrop9314]

If they don’t give you the frequency.Do you have to use the mid point to find the cumulative frequency

[@donrafaelvillaflor3487]

i believe frequency is always given
