issues. Data, even numerically code variables,
can be one of 4 levels nominal, ordinal,
interval, or ratio. It is important to identify
which level a variable is, as this impacts the
kind of analysis we can do with the data. For
example, descriptive statistics such as means can
only be done on interval or ratio level data.

same tests to answer questions about mean

single statistical testsuch as the t-testand
use it in situations calling for mean equality
decisions? (This should be started on Day 1.)
