Statistics Paper 2 19 June 2023

Good luck everybody for tomorrow! I thought the first paper was time-consuming and had some difficult questions. But I think paper 2 is going to have more questions that involve probability and probability distributions such as standardised scores, Venn diagrams, control charts, etc. And will take quicker to get the answer. Standard deviation will definitely be in the paper tomorrow as it wasn’t in the first one.

For the first paper, I didn’t really get the last question that was to do with stratified sampling, was quite a complicated question can’t lie 😳.

I got 90 but I’m sure it’s wrong. There were 6 stratas and every strata needed at least 15 people and the answer has to be the minimum answer possible. I can’t remember the total population of all 6 stratas added together . But I did ok overall. Hoping to achieve at least a 7 . Would be happy with a 9 though
