    Smile ANOVA? Looking at percentage habitat use (6 different habitats) across four seasons




    Hi,

    I am trying to look at whether habitat use of 6 different habitat types differs across 4 seasons. I have managed to run ANOVA tests but I'm not convinced this is correct. The code I have been using is as follows;

    an.aov=aov(Month~Heathland)
    an.aov
    summary(an.aov)
    other.aov=aov(Month~Other)
    other.aov
    summary(other.aov)
    scrub.aov=aov(Month~Scrubland)
    scrub.aov
    summary(scrub.aov)
    wet.aov=aov(Month~Wetland)
    wet.aov
    summary(wet.aov)
    wood.aov=aov(Month~Woodland)
    wood.aov
    summary(wood.aov)

    I thought I'd be able to run a single test with all the variables included, is this not possible? I have attached the data table below for you to view. Thank you in advance!!!

    Grassland Heathland Other Scrubland Wetland Woodland Month
    18 35 0 29 2 16 2
    14 33 0 31 10 12 7
    10 41 1 29 6 13 5
    14 39 1 30 2 14 10

    Hi,

    You haven't really described your data in a way that an expert would know what to do.

    I suggest you do the following;

    1) read the posting guidelines

    2) Carefully study this table on test choice.

    3) Know your variables, and show that you understand your data and variables when commenting here next.

    I' m sure you will be in a much better position to get help, then you would be after your above post. Random tidbits of r-code don't tells us that much either!

    Good luck,
    TE
