    Pre released material/Scientific article June 2014 (A2 biology EDEXCEL)

    where did you get this from? They only release the article before - you get the questions in the actual exam, along with a fresh copy of the article. someone else tell me if I'm wrong with this, puleeez!:eek:

    IAL Biology on may-june 2014

    wow, no teacher. That's tough. Yes, if you are going to be using t-test or mann-Whitney, you would be looking at differences between two things, so your null hypothesis would be "there will be no significant difference..." But if you are eg changing temperature and looking at enzyme activity...

    IAL Biology on may-june 2014

    Just quickly, as I'm freaking out a bit here about how close exams seem to be getting (!)... if you are comparing two populations/samples/experiments, you are probably going to be doing a t-Test or Mann-Whitney U test and you will be drawing a bar graph. If you are looking to see the efffect of...

    Scientific article is part of the Unit 5 exam from A2 Bio, If you are doing AS Bio you don't need to worry about it (yet!!!). Sorry, I try not to get into predictions - too easy to come back and bite you!

    Pre released material/Scientific article June 2014 (A2 biology EDEXCEL)

    I put these together (because I don't have a life just now!!:(). They are just general questions that should give us practice with other parts of the spec. They have all come from the Unit 5 articles, but you shouldn't need to read or sttudy the article to have a go at answering them. I don't...

    Hi, no sorry. We're doing the COPD articel because we're in an international school (I think that's the reason!). If I see anything, I will post it here.

    Pre released material/Scientific article June 2014 (A2 biology EDEXCEL)

    I think the better thing to do is focus on the article we will be using. You can always try and link in other topics from AS/A2 to the different sections of the article and then make sure you know these linked areas very well. But definitely focus finishing topics 7 & 8 as a priority!!!:eek:
