Question
Match the following attributes of a city with the appropriate scale of measurements.
Which one of the following combinations is correct?
| Attribute | Scale of measurement |
|---|---|
| (P) Average temperature () of a city | (I) Interval |
| (Q) Name of a city | (II) Ordinal |
| (R) Population density of a city | (III) Nominal |
| (S) Ranking of a city based on ease of business | (IV) Ratio |
Correct answer
(A) (P)-(I), (Q)-(III), (R)-(IV), (S)-(II)
Solution
1.Average temperature (): This is an Interval scale because it has a relative zero point (0 does not mean absence of heat).
2.Name of a city: This is a Nominal scale as it consists of categorical labels or names.
3.Population density: This is a Ratio scale because it has an absolute zero (0 people/km means no population).
4.Ranking: This is an Ordinal scale as it represents a relative position or order.
Matching: (P)-(I), (Q)-(III), (R)-(IV), (S)-(II).Continue learning with Success Tracker
