    Does anyone have the Hinemann Edexcel GCSE statistics textbook? I was looking at the practice exam paper and there was a question on Spearmans Rank Correlation, where two ranks in the table were tied. Earlier in the book it said that tied ranks would not occur on the exam...is this true? I've only been doing the course since last november (rather than starting in year 10) so our class hasn't covered a lot of what is on the syllabus

    Thanks for any replies

    Cool, thanks for that. Argh, statistics sucks so badly. I must have had some mental issues goin' on when I decided to do it as an "extra" subject. I guess it'll be all over on friday though.

    I've got the specimen and the 2004 paper. I agree it's an easy GCSE but I usually get on much much better with subjects if I find them interesting. I'm already not a very maths-y person, so statistics bores me to death :\
