    Is this A-level? To me it looks like you're working with frequencies so it would be chi squared right? If its not A-level then the chances of me being wrong are high

    Just to clarify, could you define your independent and dependent variables? It sounds like you need an independent ANOVA.

    Am I right in thinking that your DV is pre sense of staph and your IV is the pre sense of methicillin, with numerous levels corresponding to the concentration?
