Hi sir, What a wonderful video. I'm just wondering whether you will be uploading A-Level mathematics videos as they are so helpful.I'm self studying Maths but struggling a lot as I am unable to find lots of resources. Thank you so much ,I hugely appreciate the work you put in to making these videos.

[@TheGCSEMathsTutor]

Thank you so much! I have 9 GCSE lessons left to produce and then I will be focusing on the A-Level content! Almost there 🤞🏽 So glad to hear that you are finding the channel useful in your studies!

[@thearmchairanarchist9403]

@@TheGCSEMathsTutor Thank you so much sir. You are a legend. I just wondered whether you would be uploading the whole of A-Level Maths as your videos are the best on KZbin. I'm sitting the AS exam this year and I really like how your videos are taught visually with exam questions.

[@chrishendesilva3296]

Sir could you do a lesson about quartiles without the stem and leaf diagrams

[@TheGCSEMathsTutor]

I could do! It’s very much the same though just easier, you just add one to the total and then divide by 4 and count that far in from the start and end of the list! 😁🙏🏽

@@TheGCSEMathsTutor Sir please I find that topic quite confusing, it'll be really helpful if it's ur next video

[@dahlia5644]

hi sir can you do the hard interquartile questions as one of your next videos?

[@TesfuMeh]

Great content

[@JJ_TheGreat]

16:23 Question: What if you are asked to find the IQR with a number of data points, such as 24 people, for example, in which after you add 1 to it, you are left with .25 (or .75)? Would you find the fractional number that is proportionally between the two numbers (e.g., 25% above the 1st of the 2 numbers it is between)? Thanks!

[@kangietan1708]

Hi, I also use ur formula for IQR but I facing an issue here. If I have 12 data, Q1 position is 3.25, so we take average of 3rd and 4th position. Q3 position is 9.75, we take average of 9th & 10th position But if i have 10 data, Q1 position is 2.75, we take 3rd position and not average of 3rd & 4th. And Q3 position is 8.25 and we take 8th position and not average of 8th & 9th. In short, I am stuck when I get .25 or .75. Can help? Thanks.
