No, you are correct, and I am wrong! Someone commented this before and I pinned it, but I think they must have deleted it. I’ll pin your comment instead, thanks for pointing it out 😊 FYI I have updated it in the jpeg/pdf in my Google Drive so that it is fully correct 👍🏼
Glad the videos are helpful! There are ones for the other areas of the A-Level on my channel, as well as videos on all sub sections. Check them out if you get stuck, and good luck with your exams 🍀👍🏼
The modelling aspects are woven throughout the chapters, often as exam questions, and sometimes as exam questions towards the ends of playlists. I’m afraid no specific videos just on modelling as an idea though!
@@BicenMaths ah I see that’s a tricky one, my college have decided to treat it as a single topic and are including it in the statistics paper but it’s kind of hard to revise for as I’m not too sure where to look! Any specific videos you might be able to point me to?
Try these: chapter 2 Large Data Set questions ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-LfsJNzew_yI.html Chapter 3 large data set questions ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-WZ5zShiEDZg.html Chapter 4 large data set ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-9tC9mTPQM6g.html Year 2 chapter 3 modelling exam Q ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ffM_HC04ldo.html These are the kind of thing your school mean when it says modelling - questions that are in context that you have to interpret. Also check out my exam Q document in the Bicen Maths Google Drive (found on About section), as this has loads of modelling exam Qs in it. Hope they will help you!
mr bicen I cannot thank you enough for these videos you’re really a legend I went up from a C to an A thanks to you, hopefully bagging an A* this year 😅
I cba the large data set all I remember is n/a and tr apparently my teacher said the most marks ever on large data set was 5 so unless were unlucky I don’t mind
Thank you for all your hard work Mr Bicen! Your videos have been really really helpful to me. It’s a shame that when I was struggling with further pure, those videos weren’t out yet, but I’m sure future further pure students will find them very helpful!
God bless you for that little detail at 17:19. Been self teaching my self A level maths and I couldnt find the answer to that point you noted on sigma fx^2 not being sigma (fx)^2
Mr Bicen, you are a true lifesaver!! Your videos kept me from panicking right before my exams- and I'm about to walk in confidently, knowing that I have covered all of the content! Thank you for your hard work and dedication in making these videos!!
Hi Sir, How would you go about revising the large data set? No matter how much I revise it, a question always appears on a aspect of the data set which I don’t know (e.g the location of UK weather stations in the 2021 paper ) . Any tips would be appreciated !
I mean... honestly? I know the things on this video, and I know SOME of the units things are measured in. After that, I would spend my time revising other areas of the spec, as the LDS is never worth many marks, and your time would be spent better elsewhere trying to do things accurately/check them again. It's also worth noting that there are multiple answers they often accept, so have a guess and move on! (I wish the LDS wasn't in there at all!)
Hey there mr bicen you are honesrly doing a great service to students with these videos! I wanted to ask what exam board this is for or if its usable across all? Also what size paper to print this out on? Thanks Im doing edexel if that helps
Thank you! This is for Edexcel, but is largely applicable for other exam boards. Make sure you download the most up-to-date version from the Google Drive, as there were a couple of small errors in the video. I recommend printing this on A3 paper, or just 2 A4 pieces stuck together, as it is very small writing if not! Good luck!
Great vid for recalling some of the things I wouldn’t think to revise and LDS info was a life saver! Answered all questions on this paper apart from Stats Paper Q5 5 marker where all I had left to do was type in a simultaneous equation into my calculator and copy down the answer. I wonder how many marks I lost since the last thing I wrote down was the two Z=(X-mew)/StandardDeviation equations.
@@TheRealPingu It was good, 10 marker for Hyp testing think I got it. 3 marker for LDS and the rest was probability. I'm happy with it. The pure was decent too.
stupid question but i just wanted to make sure: this applies for international A levels as well right? (a fast reply would be very much appreciated cause I've got exams in a few days)
So if when you divide the number of terms you get an integer, you find the value between that position and the one above it. To be honest, they never ever ask questions like this at all, so don't worry about it!
I’ve always struggled with Venn diagrams and unions etc. I watched this video last year during when I was sitting the Y12 Maths A level and you helped me understand them so much with this method. All throughout school I struggled with understanding how to do it, but this method works so well and I have been able to do them ever since, thank you 🙏🙏
This is for Edexcel, but the exam boards are very similar. I would check carefully AQA’s guidance about finding medians and quartiles from listed data and grouped data as this can vary between exam boards. Also the Large Data Set will of course be different! But all of probability, hypothesis testing, etc. will be the same.
for approximating binomial as normal, the mean and standard deviation( which is square root of variance) formula is in the formula book under A2 discrete distribution
Hi Mr Bicen, this is really bad, I have two days left till paper 3 and don't know anything on the contents, I need an A. 😂 Its it true that theres only about 3 marks on large data set on each paper? I need to prioritize
LDS really isn't something to concern yourself with if you don't know all the content - go and learn binomial and normal distribution, and definitely Venn diagrams/conditional probability. Prioritise those for Stats!
I thought when switching from Binomial to Normal distribution, for the P(X>5) -> P(X>=6) -> P(Y>=5.5)? As 6 would be the first possible value with the binomial distribution, and -0.5 would be 5.5 in the normal distribution. Can someone please help cuz I'm freaking out over this!!
Yes - I have mentioned this in another comments that there is an error here, and also corrected it in the PDF. You must use rho (p) not r in the hypotheses.
as 12.5 is the start of that class, and you know it lies in that class because 20/2 = 10 so the 10th term will be in that one. so you know its the beginning of the class + a certain fraction along it
Thank you for all your hard work Mr Bicen! Your videos have been really really helpful to me. It’s a shame that when I was struggling with further pure, those videos weren’t out yet, but I’m sure future further pure students will find them very helpful!
hey sir how much of the year 1 content will be in the A level exam? should i just full focus on year 2 content or keep practising some year 1 stuff too?
There's always some Year 1 stuff in stats - every year there's stuff on mean/standard deviation/etc. and sometimes there's things on histograms. There's also always something on binomial distribution/hyp testing, so you'll need that too. Have a look at a recent paper and you'll get the idea of what sort of balance there is pretty quickly!
So you can replace them with 0.025mm (as this is the midpoint of 0mm and 0.05mm), or they even accept 0mm instead (have seen both allowed in mark schemes).
Convenience sampling is literally sampling in the easiest way possible - taking the first n samples of something you come across for example. It’s sometimes called opportunity sampling!
