I have % biomass increase data (3 treatments and 3 salinity variables) and would like to know which statistical test is best?
Well, It depends on how you wanna explain based on your experimental data.
one must know how and what methods to apply, which statistical methods best describe the experimental data better.
you can either use simple descriptive statistics or go for more robust regression method to explain your data.
Also Check which parameters are dependent and independent as said by Rani P Ramachandran
either you choose one dependent and two independent etc.
(Hope this help)
Thanks, I took an extra lesson and it turns out I had no way near enough data points for the distributions to make sense - they do now!
