Hi Sir, How would you go about revising the large data set? No matter how much I revise it, a question always appears on a aspect of the data set which I don’t know (e.g the location of UK weather stations in the 2021 paper ) . Any tips would be appreciated !

@BicenMaths

I mean... honestly? I know the things on this video, and I know SOME of the units things are measured in. After that, I would spend my time revising other areas of the spec, as the LDS is never worth many marks, and your time would be spent better elsewhere trying to do things accurately/check them again. It's also worth noting that there are multiple answers they often accept, so have a guess and move on! (I wish the LDS wasn't in there at all!)

Absolutely! The probability will be the most useful thing from GCSE. It’s important you really *understand* the probability concepts from GCSE as much as possible, as a lot of A-Level is built on it.

At 13:53 what's the reason Q2 wouldn't be 10.5? I saw above you said in grouped data not to round but I can't get my head around why if I had 20 things lined up the median wouldn't be the one corresponding to halfway between 10 and 11. Thanks

Yes it could come up - it follows the exact same patterns as regular conditional probabilities, but to calculate the ones you need for the formula, you just use normal distribution probabilities!
