Edexcel S2 - June 22nd, 2015 [Exam discusison thread]

Are there any topics which are in the new syllabus but weren't in the old syllabus for S2?

Posted from TSR Mobile

New? Old? The syllabus hasn't changed since 2000 (first paper June 2001).

Oh, I thought the syllabus changed in 2008 but that might just be for some of the other modules? Only asking since I did a few papers from 2008 and there wasn't anything on sampling distributions in them (the ones where you need to list all possible samples)

Yes, they thought of that a few years back as a question they could ask, and have been enthusiastically asking it ever since.

Hey anyone know where I can find the S1 thread?
I'm currently taking a gap year so im learning it myself and these threads are really helpful
thanks

What Sort of stage are people at in terms of content covered over the 3 books? I'm slightly worried my teacher is moving too slow

Offtopic but for an A* in maths, can you have C1-C4 plus 2AS modules or does one of them need to be an A2 module?

Nah you can have 2 AS modules.

What's the difference between actual significance level and level of significance ?

I'm so screwed for this exam as they're making me take it in yr12. I defo know the yr13's are gonna raise grade boundaries

Dw Yr 13s in my school wont do particularly well in it.

Like say we want a 5% significance (so that's the level of significance), but if we use the tables the closest we can get to that might be like 4.5%, which is the actual significance.

From the textbook though I'm getting the impression that:
Actual significance=probability of rejecting H0
Level of significance= probability of incorrectly rejecting H0 ?
