1. The last questions on the exam are usually binomial distribution or seasonal variation/moving averages. Well that's what I've seen on past papers ðŸ™„

I got that from the Edexcel spec. I'm not sure about AQA though... You might want to go through the spec as well.

Can someone plz tell me the advantages of a questionnaire and how to interpret srrc plz tx
SRCC is a value between -1 and 1. A value close to 1 means a strong positive correlation and a value close to -1 means a strong negative correlation. Everything close to 0 is weak or no correlation. Hope this helps!!

One question. for spearman's rank, what happens if 3 values are the same. What is their rank?
You just give the mean of the 3 values. e.g. 1,2,4,4,4,6,7,8 and so on...
The values for 3,4,5 are the same so you just find the mean of those 3 numbers and that is their rank.
It should be the same for 4 values or 5 values.
