A tipical Example from Literaure

A classical way to indicate the procedure in statistical analysis of manuscripts dealing with in vitro toxicology: “Data are shown as mean (SD or SEM) of at least n independent experiments. Each experiment was conducted in n-replicates. P<0.05 was considered significant performing t-test or ANOVA with a given post-hoc test”. This statement however says nothing about how the data are treated. I will show you several different ways with some advantages and disadvantages to take into account or not both the number of experiments and replicates.
