Edexcel Mathematics Paper 3 (Statistics & Mechanics)
Date: 19 October 2020 Session: PM Length: 2h Marks: 100 (a third of the total A-level)
Paper 3 can cover anything on the Statistics & Mechanics part of the specification.
If you want to use old spec resources, there is a content mapping document here. Be aware that the style is different and the old specification does not cover everything.
Question when do i use 2 - variable on the calculator and when do i use 1 variable or is it 100 percent 1 variable everytime for exams pls quick i dont have much time till monday

I haven't seen any questions that use 2 variable tbh i think it's just 1-variable? Make sure you have the freq column tho for 1-variable
Anyone else in agreement that this paper could be around the same difficulty as last years paper 3 (i.e relatively easy) considering the first 2 papers have been quite tough? Or are we expecting a third hard paper as well?

thatβs a good argument but itβs best not to assume an exam is easy. Iβm gonna revise like itβs the 2018 stats and mechanics paper.
you do need the 2nd variable actually for work out product moment correlation coefficient
Was just about to ask do we still need to know regression but thanks that solves it i havent seen it in so many edexcel papers but i dont trust edexcel
if i get 50 on paper 1 70 on paper 2 and 90 on paper 3 do i still get the a* cause my overrall was higher than the a* grade or is that a no?
Nope, that would add up to 210 so you'd still get an A. The grade boundaries for individual papers are just notional, i.e. they don't really mean anything in an actual exam series. They just publish them because they recognise that it may be useful as a 'guide' in e.g. mocks or when you're revising. But the only thing that's important in the real thing is what your total marks are out of 300
what are the predictions for paper 3 considering topics that were tested in 2018,2019?
Be prepared to see some conditional probability questions like they did in the 2018 paper on the battery question as if I recall correctly they did not ask a conditional probability question in 2019 for a binomial/normal distribution question.
