Tetrahymena

In an experiment with the unicellar organism tetrahymena
(Hellung-Larsen et al., 1990), we are interested in determining how
cell concentration may affect the cell size (average cell diameter).

Moreover, the effect of adding glucose to the growth media is
investigated, by studying 19 cell cultures with no glucose added and
comparing to 32 cell cultures grown with glucose added.



Variable list:

glucose:	Presence of glucose in the groth media
        	0: No
        	1: Yes

concentration: 	Cell concentration 
               	(number of cells in 1 mL of the growth media)

diameter: 	Average cell diameter (measured in µm)
