Quantitative data can be measured by which type of scale? Ordinal Nominal Interval Both A and B

To determine which types of scales are used for quantitative data measurement, we can analyze the options provided:

1. Ordinal: This scale indicates an order or ranking among items but does not quantify the difference between them. Therefore, it's not suitable for measuring quantitative data.

2. Nominal: This scale categorizes data without a meaningful order or ranking. It is used for qualitative data rather than quantitative data.

3. Interval: This scale not only indicates the order but also measures the exact differences between values. It is indeed suitable for quantitative data because it has a meaningful zero point and equal intervals.

4. Both A and B: This option suggests that both Ordinal and Nominal scales are relevant for quantitative data, which is incorrect based on our analysis.

Final Answer

The correct option is "Interval," as it is the only scale that allows for measurement of quantitative data.
