Afarm cooperative has asked you to design an experiment that measures the
effects of light exposure on the growth of tulips in the skagit valley of
washington state. you hypothesize that tulips exposed to more direct light will
grow at a faster rate than those exposed to less light. you also wonder whether
the effects of light exposure persist when you control for the amount of
moisture the plants receive. you want to create a randomized comparative
design that considers three factors with the following levels:
light exposure (no, yes)
amount of light exposure (3 hours a day, 6 hours a day, 9 hours a day)
amount of moisture exposure (1 hour a day, 3 hours a day, 5 hours a day)
you have 1,000 seedling plants at 12 different nurseries to use in your
experiment. your experiment should run six months in length. outline the
details of your experiment.
in your answer you should comment on a strategy for randomization, identify
all the possible treatment groups, and discuss what might be a possible
response variable. in addition, you should identify a couple confounding
variables and discuss a method of controlling for one of these variables. as
much as possible, use diagrams instead of words to summarize your
experimental design.
