I have evaluated my experimental data now.
It looks like my data shows that levels in the college are higher than average (2/3 rather than 1/3) however my data is incredibly unreliable in this because only three people were sampled. I would need a much larger sample to draw any real conclusions, but that cannot be done with the resources available. This data will still be very useful to put in my essay however, as it will provide me with an opportunity to talk about levels of bacteria in different places.
