GCSE Statistics exam 2015

In two days, I have my GCSE Statistics exam (Edexcel) and I don't know how to start revising, but could anyone provide some questions about standard deviation and probability? (These are the areas I'm weakest on). Also, can anyone who's done it, tell me what sort of same questions/topics have popped up in the past few years?

I got an A in my course work (31/40) but I would like to get an A* overall so what mark would I have to get in the exam, in order to achieve this?

Any help will be appreciated

Hi, I'm in year 9 and doing this exam too! I got 29/40 on the coursework and my teacher said I had to get 70-80% for an A/A*. To revise I would recommend just practicing a couple of papers before Thursday. Does your school have MyMaths, I would also recommend going through their sections on standard deviation and probability. Remember you don't need to learn the formula for standard deviation off by heart because it is at the front of the paper.

Here is a link to a page with past standard deviation questions. There are videos that go through how to solve most of the questions along with the full paper and mark scheme!

The same website also have stuff on probability that might be of use to you, here:

Hope this helps and let me know how you get on!

Yh I got the exact same marks in my coursework, we're in the same situation. I've looked at past grades and ums u would need approx 85 marks aim for 90 to be safe that's what I'm doing

Hello! Thank you so much for taking your time to reply back to this thread and providing some useful websites!

I've found another website which may be useful to you as well, as you're also doing your exam:

https://www.tes.co.uk/teaching-resource/gcse-statistics-revision-exam-questions-6401597

It has 4 revision packs on standard deviation and spearman's rank, probability, data collection and processing data (if you're also with Edexcel).

I found these really helpful and I just thought I'd share as you helped me out

I wish you good luck on your exam and I'll be sure to let you know how it goes!

Thanks for the rating much appreciated how did you find the exam? I thought it was easy compared to some of the past papers I have attempted!

My teacher never even told me what I got in my coursework :/

Hiya! It was easy wasn't it! I only mucked up on geometric mean, comparitive pie chart and the chain index number so I reckon I didn't lose to many marks.

Hello! Yes I did find it quite easy, but there weren't any geometric mean and comparative pie charts in my exam; by any chance, is your exam board AQA? Some of the topics that came up for me was cumulative frequency, probability, box plots etc. I got told today that I didn't have to know the geometric mean formula because Edexcel don't have questions on that topic? Glad to know you didn't lose many marks, no matter what, I'm sure you did well!

You're welcome! It was actually easier than I expected (most people in my year told me that this year's paper was going to be nasty..) I thought the 2014 paper was quite hard but luckily there were no questions on venn diagrams and not much on probability . I'm still nervous though, after the exam but, nonetheless it's over and done with! I'm glad you didn't find it too bad, I'm sure you did well! I'm getting my result on the 20th August, I assume that's when you'll receive yours too?

Anyone know or have the grade boundaries?

You should be fine. It might be marked by hand though - but its good
