Hey all, I'm investigating the effect of substance x in varying concentrations on either of these:
ONLY the seed germination in plant y OR the seed germination AND subsequent growth of plant y.
I've received conflicting feedback with people saying one DV will give sufficient data whereas the official IB exemplars investigate both germination and growth. I would much rather investigate both DVs than 1 DV as I would find the entire experiment much more interesting and I'd have more fun writing the report, I also believe I can comfortably fit all the data I need from 2 DVs within the page lim
