How you set up your experiment is determined by the question
you wish to answer. Also when doing an experiments such
as the one you propose, you should have at least three
plants per treatment, not one. This allows for simple
statistics plus it gives more credibility to your results.
If all of your plants in one treatment look similar, you can
have more faith that the observed result came about because
of the treatment.
Now, getting to the question:
The first question of the two would be the easiest to study.
You could use different concentrations of coffee ranging
from very weak to very strong. Remember, for every con-
centration of coffee you need to look at the same number of
plants. The reason you should use many concentrations of
coffee is you don't know which concentration might be
effective. Maybe at low concentration you might see an
one effect and at high concentrations another effect might
be observed. Good luck.
