    theres your null hypothesis, which is a BIT like predicting your results.

    I went for people because I hate plants. But people mean you've got to worry about ethics and potentially messing them up mentally and stuff :/
    Sorry I don't understand what you mean by this?

    and we were kinda forced to do plants or aquatic animals coz we went to a field :/

    O_o. You've not been told about a null hypothesis!! Basically your null hypothesis says that there'll be no difference between your two sets of data. So something like 'there will be no significant change in leaf area between the two areas'

    Glad they are useful! Any other questions would be greatly appriciated! I think there defo will be a synoptic link with unit1,4,. How are you guys finding neurones? Weve finished brains, and returning to neurones.

    We have just finished today and started analyzing the article.

    I'm from Jordan, and Easter holiday is just one day here. Muslims don't take any day off, while Christians take 1 week.

    Hey guys, i posted this in another thread earlier... I was wondering if anyone here could help me out too. It's about coursework.


    My hypothesis for my investigation was that there would be a significant difference between the abundance of limpets on lower, middle and upper shore levels.

    I carried out a Mann Whitney U Statistical tests on my data.
    The first test compared lower and middle.
    second - middle and upper
    third - lower and upper

    The test indicated that there was a significant difference between lower and middle, and lower and upper, but not between middle and upper....

    There was therefore, overall, a significant difference. However, not completely..

    Does that mean that I should accept or reject my hypothesis? It is acceptable to 'partially' accept your hypothesis?

    Do a Chi-squared test; it will give a clear-cut answer.

    This is quite random, but I expected that it would have been about the sport side of the topic what with the London Olympics knocking on the door!
