Imagine you were conducting an environmental impact analysis,
where you recorded the following levels of mercury concentrations
in several lakes. The table below shows the number of lakes with
different mercury concentrations in the water.
This information will be used to determine what threshold to set
for “safe” concentrations of mercury, and the number of lakes that
will need remediation (the number above the “safe” threshold).
Given this scientific goal, which measure of central tendency would
you report for this data set to summarize it?
Select one:
a. The mean
b. The maximum value
c. The mode
d. The median
