What type of data is classified as subjective data?

Subjective data is characterized by its reliance on personal opinions, interpretations, feelings, or beliefs rather than on objective facts. The correct choice captures this essence by highlighting that this type of data is often non-measurable and typically obtained through methods like surveys or interviews, where respondents provide their perspectives or reactions to questions.

In contrast, the other options pertain to objective forms of data. Quantitative data that can be analyzed statistically is inherently objective, as it is based on numerical values that can be measured and compared. Scientific experiments yield data that is usually objective and factual and can be replicated. Similarly, measurement data that can be numerically expressed is also concrete and falls under the realm of objective data. Thus, the distinction lies in the nature of the data—subjective data captures personal insights, while the other types pertain to empirical, measurable information.
