    Spread of data around the mean. Mean is the magic word for which you get the point (according to mark shame). From mathematical point of view it may be to simple but it is all required for purpose of module 5.

    I think u do need to know chi squared, it is basically a statistical test to see whether your results can be accepted as experimental and not just down to chance factors

    I normally pick up things quickly and can revise easily. The reason I'm finding this module hard is because it's so god damn boring. I just can't wait till the 24th of June where I can safely say I will never study Biology again.

    I've done modules 1-4, got 312/390, an 'A' (just). I got 36/38 on coursework. Of the 210 remaining marks, how many are courswork? 66 or 45?

    Courswork is out of 66. Well done by the way, I have only got 32/38 (our teacher is always so strict on courswork :/). But I do not care, I just need 110 marks out of modules 5 and 8.

    i have this and i need an A or B and i really suck at biology (i got an E at AS). im panicking but i don't know how to prepare for it well. i cant link the stuff in the textbooks to the way the questions are asked.

    The actual specification content is fine, but the wording of the questions is the REAL problem

    the best thing you can do is look over some past papers and it might help you link everything together

    bump to that

    just printing the last module 5 paper to do (jun 04)

    doing past papers is the best thing I think, thats the only way to get used to what answers they want. You can write a "correct" answer but it may not be what the mark scheme wants - so check over some past papers and mark schemes, if u havent already:

    http://www.aqa.org.uk/qual/gceasa/bioB_assess.html

    From the examiners reports, the average A grade for module 5 is about 40/66 which is 60%. For module 4 it is about 50/81 = 61.7%

    In the examiners reports, go right to the bottom and youll see the % and equivalent UMS scores for each paper that year.

    EDIT: in chi squared ****, allways use the word "significant". A result is deemed significant if the chi squared **** is less than 0.5, I think - thats the chance of the results being ******** and due to chance - or the chance of the null hypothesis being fo real. So if u have to analyse the results, mention their **significance**

    If the CS value is better than the reference value for 0.05 or 5% at the correct degrees of freedom.
