A statement involving scales of measurement is called meaningless if
its truth or falsity can depend on the particular versions of scales
that are used in the statement. Using examples from the study of
landscape ecology and environmental sustainability involving indices
of biodiversity, global vegetation indices, metrics of climate change,
and others, we will give a variety of examples of meaningless and
meaningful statements. We will briefly discuss the mathematical
foundations of the theory of meaningfulness, discuss ways to average
scores that lead to meaningful statements, and, time permitting,
discuss the meaningfulness of statistical tests.
