Statistical design of biological research

ECOSTAT can assist you in choosing an experimental design which is statistically sound. We indicate which design is the best to answer your questions while fitting within your budget and also meeting your other conditions.




Some examples of ECOSTAT's experience

  • Development of statistics and experimental design for several laboratory ecotoxicological bioassays (with the crustacean Corophium, the sea-urchin Echinocardium, the rotifer Brachionus and larvae of the oyster Crassostrea, among others. One of these studies is described in van der Hoeven et al., 2002
  • Investigation into the number of replicates needed for the desired power in a field experiment with a herbicide.
  • Investigation in the number of replicates and sub-samples needed in an ecotoxicological and histopathological study with fish (Pimephales) and snails (Marisa).
