Which report gives basic observer data?

• A. Report Four
• B. Report Two
• C. Report Five
• D. Report One

Answer: (D)

Basic observer data means the raw, directly recorded observations from the observers—the unprocessed notes, times, identifiers, and any immediate measurements. Report One is the one that provides this kind of data, giving the original entries without added analysis or interpretation. The other reports tend to present summarized, calculated, or interpreted information derived from those observations, rather than the raw inputs themselves, so they aren’t the basic observer data.
