Referring to the previous exercise, two possible data tables are shown in the following table . Which one has the observational units right? Why?

Data from previous exercise

Alligators have become a big concern in Florida. Here are some gator data.

The rows are for five small Florida lakes. They stretch along a line from the west coast near Tampa to the east coast. The columns are for years, spaced half a decade apart. The counts tell the numbers of alligators harvested. (Data source: myfwc. com/mediaˆ™1357388ˆ™Alligator_Annual_Summaries.pdf.) Look first at the column totals: Is there a trend over time? Then look at row totals: How do lakes compare? Finally, think about association. Is the pattern over time pretty much the same for all five lakes?
