    Hi there I need some help! What statistical tests should i use/consider (pref in SPSS) in regards to an invertebrate survey i have carried out comparing urban street trees to urban park trees. I am looking at species richness and abundance between the two sites and also other variables such as tree species, tree width at base, distance from road/tarmac, tree base substrate and weather at time of collection. any help would be greatly appreciated!

    If your data is normally distributed which I assume it will be, possibly a Multivariate Analysis of Variance/ANOVA? With your dependent variable being either the species richness or abundance (depending on which you're testing), and your fixed factors being your Location/Distance from Road/Tree Base Substrate, and Weather?

    I'm not particularly great at stats, so the chances of me being corrected is probable .

    Cheers,
    Jamie.
