    Also how do you know when the standard deviations are overlapping and what does this mean?

    Standard deviations show how far the values were away from the mean. The larger the standard deviation the more inaccurate the results as there would be a large range around the mean.
    If the standard deviations overlap then it is likely that the investigated variable isn't having much of an effect, if any as some of the same values were recorded in both experiments for instance.
    Overlapping standard deviations when looking at species would suggest that they are the same species, e.g if head size for instance overlapped then it is likely that the two organisms aren't separate species
    hope that helped x
