I'm developing an assay to determine sensitivity to a hypomethylation chemotherapy agent. Preliminary cytotoxicity assays were conducted to determine dosages that yield the optimum viable cultured cell count to hypomethylation ratio via Trypan Blue & Cell TitierGLO assays. In the attached file you can see i have graphed the data with error bars. Is it necessary to conduct any more analyses via using methods such as ANOVAs?
