A collection of information in a table has been arranged as satisfied, very satisfied and dissatisfied. Which of the following will be the right term for such information?
**Core Concept**
Ordinal data is a type of quantitative data that has a natural order or ranking, but the differences between consecutive values are not necessarily equal. This type of data is often used in surveys and questionnaires to measure attitudes, opinions, or satisfaction levels.
**Why the Correct Answer is Right**
The information presented in the table has been arranged as satisfied, very satisfied, and dissatisfied, indicating a clear order or ranking. Although the differences between consecutive values (e.g., from satisfied to very satisfied) are not equal, the data still retains a natural order. This characteristic is typical of ordinal data, which is often used in social sciences to measure subjective experiences or opinions. In this case, the term "ordinal data" is the most suitable choice because it accurately reflects the ordered nature of the information.
**Why Each Wrong Option is Incorrect**
**Option A:** Interval data refers to a type of quantitative data that has a natural order and equal intervals between consecutive values. However, the information in the table does not meet this criterion, as the differences between consecutive values are not necessarily equal.
**Option B:** Ratio data is a type of quantitative data that has a natural order, equal intervals, and a true zero point. The information in the table does not have a true zero point, making ratio data an incorrect choice.
**Option C:** Nominal data is a type of qualitative data that has no natural order or ranking. The information in the table, however, has a clear order or ranking, making nominal data an incorrect choice.
**Clinical Pearl / High-Yield Fact**
When dealing with survey data or questionnaires, it's essential to recognize the type of data being collected to choose the correct statistical analysis method. Ordinal data often requires non-parametric tests, such as the Wilcoxon rank-sum test, whereas interval or ratio data may require parametric tests, like the t-test.
**✓ Correct Answer: D. Ordinal data**
