Which measurement scale should be used to measure temperature?

• A. Nominal
• B. Ordinal
• C. Interval
• D. Ratio

Answer: (C)

The measurement of temperature is most appropriately categorized as an interval scale. In an interval scale, the difference between values is meaningful, which is true for temperature. For example, the difference between 10 degrees and 20 degrees is the same increment as the difference between 20 degrees and 30 degrees; both represent a change of 10 degrees. Additionally, on an interval scale, the zero point is arbitrary; for example, 0 degrees in Celsius does not mean 'no temperature' but rather a specific point on the temperature scale. This property distinguishes interval scales from ratio scales, which do have an absolute zero that indicates the absence of the quantity being measured. Using an interval scale for temperature allows for a wide range of mathematical operations and comparisons. Therefore, it provides a precise means of measuring temperature changes, making it the suitable choice for this particular context.
