For example, even discrete quantitative data can be thought of as arising by a process of “measurement through counting.”

Answer 2

1. Nominal
2. Ordinal
3. Interval
4. Ratio

Question 3

are qualitative only.

• Data at this level are categorized using names, labels, or qualities. No mathematical computations can be made at this level.

Answer 3

Nominal

Question 4

level of measurement are qualitative or quantitative.

• Data at this level can be arranged in order, or ranked, but differences between data entries are not meaningful.

Answer 4

Ordinal

Question 5

When numbers are at the nominal level of measurement, they simply represent a

Answer 5

Label

Question 6

level of measurement can be ordered, and meaningful differences between data entries can be calculated.

• At the interval level, a zero entry simply represents a position on a scale; the entry is not an inherent zero.

Answer 6

Interval

Question 7

level of measurement are similar to data at the interval level, with the added property that a zero entry is an inherent zero.
• A ratio of two data entries can be formed so that one data entry can be meaningfully expressed as a multiple of another.

EXAMPLE
1. Weight
2. Age
3. Salary

Answer 7

Ratio
