Factorial ANOVA for Number of Colonies

The purpose of this analysis is to perform a Factorial ANOVA analysis in order to assess the effect of three independent variables (factors) which are Concentration, Cell Line and Drug on one dependent variable, which is Number of Colonies .

For the purpose of the analysis, a 4 x 2 x 3 Factorial ANOVA design will be used, with a sample size of N = 672. The following descriptive statistics are obtained:
