That'd be only like 2 marks though right? Like the solution makes starch go blue/black.

lol

Pretty certain one of the diseases for either heart or lung will come up ... pretty much comes up every year if im not mistaken. Immunology is also likely to come up since it's probably the most difficult topic to get your head round (seperates candidates well for boundaries).

Its hard to help without having a question, as you need to refer to the actual graph and text and stuff but generally you just need to state:

1) Graph shows correlation. (Say whether its positive or negative)
2) Correlation does not show causation & state another factor which could effect the results (e.g smoking, high blood pressure, really depends on the results though.)
3) Look really hard at the graph and see if theres any anomolous data or data which would disprove the conclusions/correlation. (e.g There was one about deaths vs fat in diet per country, or something similar, and one country had the same amount of fat in diet as another, but one had wayy more deaths than the other.. so mention that this would go against the positive correlation)

I'm not really that bothered as it hasn't affected my reputation as I've been given positive reputation elsewhere, but it would be nice to have an explanation to go with it and to have a name to the negative given I don't subscribe. I mean, if I was trolling or making completely inane posts and being purposely unhelpful and misleading, then I would deserve it. I don't feel I do deserve it.

In that case I'll quietly allow it to happen.

Also, I did post some questions early this morning. I don't know if you've seen them or done them.
