Hey, who is doing this exam? Have you all started revising for it?

Thought I would make this thread as there are a few general statistics threads , but not one specific to this exam board(not that I could see)

Here's the link to some past papers you might want to have a go at or look through.

What are people actually revising for statistics? I mean I know a lot of it's just common sense, but do we need to know binomial, standard deviation, PMCC e.t.c? My maths teacher jst focused on the FSMQ for the past 2 years, so I know nothing! HELP PLZ

Anyone know about standardized death rates? Usually in past papers they give you the standard population but I'm not sure if they give that in our paper

You need to have an awareness of standardised rates

- they take in account age distributions of people living in an area, so you can compare 2 areas more fairly
- if an area had more over 60s than another it's likely to have a higher standardised rate.
-

You don't need to know how to calculate it, as this was removed from Ye specification

Hope I helped

You do not need to know binomial distribution that's edexcel.

You do need to know about pmcc and sd

I would look at the specification, if you're unsure on what to learn

For 10d it's 75 % as 21/28*100=75. We are told that 21 deliveries are completed in under 21 minutes and the total sample is 28.

10dii it's 28 * 4 =112
