Case Example: Phelpsicillin


Let's consider an experiment which involves testing the toxicity of a new type of drug called Phelpsicillin.  This drug is exposed to 3 different cell types in culture, and the cell survival rate is quantified.  The variables stand for the amount of time in days after which only 50% of the cells in a specific petri dish are left alive.
