Question
Determine which of the four levels of measurement​ (nominal, ordinal,​ interval, ratio) is most appropriate for the data below.
 
Blood lead levels of low, medium, and high
 
 
 
Choose the correct answer below.
 
 
A.
The
nominal
level of measurement is most appropriate because the data
cannot be
ordered.
 
B.
The
ordinal
level of measurement is most appropriate because the data
can be
ordered,
but
differences (obtained by subtraction)
cannot
be found
or are
meaningless.
 
 
 
 
 
C.
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.
 
D.
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
