Levels of Measurement
• The nominal level of measurement is
characterized by data that consist of
names, labels, or categories only.
• The ordinal level of measurement
involves data that may be arranged in
some order but differences between data
values either cannot be determined or are
meaningless.
Levels of Measurement
• The interval level of measurement is
like the ordinal level, but meaningful
amounts of differences can be determined.
It has no inherent (natural) zero starting
point.
• The ratio level of measurement is the
interval level modified to include the
inherent zero starting point.
Identify the level of measurement for each of
the following data.
1. Blood type of a patient admitted to a hospital
2. Intelligence Quotient of a student
3. Tax identification number (TIN) of an
employee
4. A student’s academic rank in high school
5. Average daily sales of a bakeshop
6. TV network
7. Most popular movie actor
8. Birth order in the family
9. Body temperature
10. Memory capacity of a computer
