Cumulative Frequency

[@mekizfreen]

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!!!!!

thank you so much for this video, im literally on the verge of breaking down from frustration. u explained this better than my friends and teachers good job 👍👍

What if the data is inclusive then do we first convert it to exclusive data?

thanks for explaining it so well . I understood everythin

[@zak30]

its been 3 years what are you doing now out of curiosity

[@treeing]

'hummm. that is not possible :) ' , I can't believe it only 2 watched commented out of 906?

[@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

[@ahmedkamran7316]

Thnx fr the explanation bro

[@tooth5276]

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

[@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.

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

*10 seconds later* i understand..

[@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 ?

[@thitsarkhaingwo236]

I dont know how you calculated the median ..

[@savvaseleftheriades7291]

Great vid but at 9:27 you say the median is measured from 30 not 35

[@mathsgenie7808]

If there are 60 people the median is at 30.

[@mst6470]

@@mathsgenie7808 I thought that if the frequency was 50 or less, the median would be (n + 1)/2, but here you divided by 2 without adding 1. Please explain 🙏
