I don't think S1 exists, I'll have a look and if not I'll make it now.

In the book it does say a continuity correction can be applied depending on a question. It is definitely in the chapter 3 somewhere in a red box where they write comments.


Can you tell me the page number?

I know that theoretically it makes sense - in fact, most other boards use a correction of ±12n\pm \frac{1}{2n} after using the CLT, where nn is the sample size. But Edexcel doesn't follow it for some reason.

The questions on random numbers in the book are not so great :s-smilie: I guess in the exam, just pick the numbers in a random way (eg going down a column or across a row), say what you're doing and .... I think that works.

When you expect an add further maths student to pick out random numbers from a chart 😂

It's been too long, I'll have a look at the most recent ones and see if it pops up.

Ah, it kind of half-came up in the paper I sat, question 1. But no need to use the tables here, just to appreciate them.

They brought an exponential function for the MLE in my exam. It was really easy. Thanks for your help the other day 😊

I'm at uni. And no, they gave a specialised function. Also, I thought you said that MLE wasn't a part of A levels?

I know you are :tongue: you get UMS, sort of, at uni as well. At least, I do! It's just not as clear/transparent as at A-level.

Lol I can never get full marks in anything, I make too many mistakes.

At levels I had 100 UMS knowledge but I'd never actually get it. It's always 97, 95 lol so annoying.
