Here is a list of experiments designed and conducted by teams in the Tuesday Bios 211 class of Spring 2001. Both raw data and summary statistics are presented, along with a brief critique of each experiment as described previously . Methods were as outlined for the carbon fixation experiments .
Counts are quite low - equivalent to controls incubated in total darkness.
Something was clearly not right. There is considerable disparity in counts among samples. With this much variability it is clear from inspection that there will be no significant difference observed between leaf types. It is very likely that there was a difference in conditions between the two dishes - likely a difference in amount of radioactivity retained in the atmosphere. There is clearly no significant difference between means, and data scatter is not too bad, for this type experiment.
