this is my dissertation:
I grew an algae called Chlamydomonas reinhardtii in square petri dishes with coloured filters on top to see whether they would swim to the best light or stay where they were and adapt even if it wasn't the optimal colour of light. I used 3 treatments of coloured filters:
shallow = a single rainbow from one side of the dish to the other
medium = two rainbows from one side of the dish to the other
steep = three rainbows from one side of the dish to the other
and a control which had no coloured filters.
This means it is easiest to adapt in a shallow treatment where the area of each colour is in a single large block rather than split up into 3 as in the steep treatment.
The results look like this:
Figure 1: Natural log of the proportion of Chlamydomonas reinhardtii cells (ln(proportion of cells)) observed at each colour between shallow (dark blue), medium (pink), steep (yellow) and control (light blue) treatments. All data points represent averages with +/- standard error of the mean. The control had all colours available at all locations and therefore represents a random distribution.
Hopefully it looks nice and shiny. My problem is although those colourful lines look very different to one another I'm having problems figuring out how to statistically prove they are different. I don't know if any of you can help but I think i've been over thinking it so I figure someone out there has an easy solution.
Also let me know if anyone actually understands what this shows. That would mean I'm on the right track. Only 5 days till it's handed in. No sleep for me.
