A group of ecologists want to test if an industrial effluent affects the diversity of aquatic invertebrates in a river. To do this, they compare the community of aquatic invertebrates between two sites: one upstream of the effluent and one downstrean of the effluent. Which variable should they calculate to compare the diversity of the two communities of invertebrates?
