Hello!
I'm trying to plot my results in a single graph/table, in Graphpad Prism. And I need to perform statistical analysis. But I am not able to accomplish this.
Basically I have different samples (A, B, C, D, Control) in three concentrations (1, 2, 3 for ABC, while the negative control = 100%), in a single time (24h).
How should I organize this table and what statistical test can I apply?
I am unable to perform Two-way Anova + Tukey, because the reported results that I obtained differ compared to One Way Anova for each sample isolated at different contractions compared to the negative control.
I manage to do the Two Way Anova when I use the same concentration but at two different times (24, 72h), but this is not satisfactory, as I need to compare the different samples with each other, at the same time (24h), with different concentrations.
