An appraiser inspects a subject property, which is a vacant apartment building. The appraiser's measurements and field notes from the inspection would be considered what type of data?

• A. Primary Data
• B. Specific Data
• C. Secondary Data
• D. Tertiary Data

Answer: (B)

Data gathered directly from the subject property through inspection are collected firsthand for this specific assignment. That makes them specific data—data obtained for a particular property. They aren’t pulled from published sources (which would be secondary data) and they aren’t a summary or compilation of existing information (which would be tertiary data). By being measured and noted on site, these observations are created for this property’s appraisal, fitting the "specific data" label used in this context.
