Which term describes data that are derived from field observations and often qualitative in nature?

• A. Temporal Data
• B. Qualitative Data
• C. Raster Data
• D. Quantitative Data

Answer: (B)

Data gathered from field observations that describe qualities or categories rather than numbers are qualitative data. This kind data captures attributes, classifications, and descriptive notes—like land cover types (forest, grassland, urban), presence or absence of features, or observations about color and texture—written or coded as categories. It emphasizes what is observed rather than how much or how many, so its primary form is non-numeric. Other terms describe different aspects: temporal data relates to time, raster data refers to grid-based imagery or surfaces, and quantitative data are numeric measurements. So the best fit for data derived from field observations and often descriptive is qualitative data.
