Tetrahymena data
Table of Contents
Description
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.
Variables
| Variable | Explanation (Unit) |
|---|---|
| supplement | "glucose" if presence of glucose in the groth media or "none" |
| concentration | Cell concentration (number of cells in 1 mL of the growth media) |
| diameter | Average cell diameter (measured in micrometer) |
