You make lovely videos and they are greatly helpful and very clearly understandable. Really appreciate what you are doing for us students. Really really helpful!!
This is such a lovely comment - thank you for taking the time to write it! I’m passionate about maths education, so this makes me really happy. Thank you! 😃
7:59 if we look at the data from the left to the right, then isnt 75% of data more than 0? How did you assume that 75% of the data is exactly 7000 more? I dont get it fully here 😭
The lower quartile line of the box plot is at 7000 - and by the definition of the lower quartile, this means that 7000 is one quarter of the way along the data. So three quarters of the data must be 7000 or greater :)
Yes I will be working on these videos this coming week - I got a bit distracted making some other content, but will continue with this playlist next. Pleased they’re helping you!
Skewness is definitely not included in the current specification - but it was in the previous version, which is why you’re probably seeing it coming up! No need to learn it.

for 8:00 why do we consider the 25 percents from the maximum value and to the left instead of going from the minimum value to the right?
Because they are saying that 75% is more than a particular value, so 25% is less than that value.
@@BicenMaths Sorry im late, but thank you for all the help along these exams 🙏 Your videos were really helpful 💯
Will you be doing cumulative frequency soon? These videos are saving my year 12 maths thank you!

Same here! Thank you very much!
on 7:10 how do we know its only 7000 and not lets say 8000 or 10000 like they say?
Just because we can read that the LQ is exactly at 7000, so that means 75% are higher than 7000
Hi sir, is skew something we are expected to know and are we expected to compare it with other box plots?
No - skew is 100% not included in this spec - you might see questions with it as it was on the previous spec from 5 years ago 👍🏼
can you please do a video for 'everything you need to memorise for pure 3 A level mathematics'? The one you did on mechanics was sooooo helpful!!!!
You mean for A-Level Pure? It’s right here! ua-cam.com/video/OnZGBQyWK1g/v-deo.html
Hi Sir, I've seen a couple exam questions online about box plots and I was wondering "what the skewness of the data" means.
Skewness is definitely not included in the current specification - but it was in the previous version, which is why you’re probably seeing it coming up! No need to learn it.
@@BicenMaths I thought so, I couldn't find it anywhere in the textbook! Thank you for letting me know, I appreciate it.
IQR range, isnt that Interquartile range range?? 9:22
Yep!
