Determine which of the four levels of measurement (nominal,
ordinal, interval, ratio) is most appropriate for the data
below.
Course grades from A to F
Choose the correct answer below.
A.
The nominal level of measurement is most appropriate because the
data
cannot be ordered.
B.
The ratio level of measurement is most appropriate because the
data
can be ordered,
differences (obtained by subtraction) can be found and are meaningful, and there is a
natural starting point.
C.
The interval level of measurement is most appropriate because
the data can be
ordered, differences (obtained by subtraction) can be found and are meaningful, and
there is no natural starting point.
D.
The ordinal level of measurement is most appropriate because the
data
can be ordered, but differences cannot be found or are
meaningless.
