Assumed methods statistics for specialist units 3 and 4?

[BiggestVCESweat]

I took methods last year, and due to the coronavirus we didn't do the majority of probability and statistics.
What parts of Methods probability are assumed for specialist units 3 and 4?

In particular, which sections of methods probability required for specialist units 3 and 4 does the Cambridge textbook not include in their specialist 3/4 textbook?

The bare minimum that you need to know for 3/4 specialist is what a random variable is (check) and what the normal distribution is (double check). That's it - if you have those, then you're golden.

I do, however, also recommend looking up expectation and variance as well as how they are calculated, and doing a couple of practice problems and calculating them for yourself. It is also worth your time to look up and read (not do questions for, but have an understanding of) the difference between a population parameter and sample statistic, as well as some of the simulation stuff and the calculating of a proportion confidence interval (not for the proportion part, just for the confidence interval part). Again, with the exception of variance and expectation, this last stuff you won't need to know how to do, but having an acute understanding of what they are will be beneficial, because they may not be explained in your specialist text book since it IS assumed knowledge from methods.
